Why You Should Choose a Laptop Repair Service Vs DIY

Laptops are great machines. The ability to carry everything with you in a compact unit, set up anywhere and work, online if there is access to WiFi, is priceless. But when things go wrong, it can be terrible.

When your laptop has everything on it from birthday reminders to the slideshow presentation for work, having something go wrong can be a very stressful event. Unlike desktop computers, laptops are not very conducive to DIY repairs and it`s best to find a someone who does laptop repair in Toronto.

It`s not easy finding someone who is qualified to make repairs on your laptop. Toronto is chock full of so-called computer experts who may know a thing or two, but what they don`t know could destroy your computer. Laptops are far more delicate than most people suspect and it`s not a great idea to let just anyone muck around in there. If you care about your computer, you`ll want to ensure that you find someone who will do a good job and who has plenty of experience.

You will no doubt pay more for a true repair service. It`s worth it, though, since the downsides are many if you opt for a hack job at half the price. Some of the problems associated with people advertising as laptop repair specialists without actually being qualified include the following:

o Loss of data. You risk losing everything on your hard drive if you let the wrong person mess around. Trained laptop repair specialists will be able to either repair your computer without damaging your data, or they should be able to extract it for you, in the case that nothing more can be done for your laptop.

o Security. Not everyone is on the straight and narrow and if you have private info on your laptop, that`s going to be out there for the repairman to see, so make sure you find someone trustworthy to do the job.

o Theft. Sadly, there are a few people who pose as a laptop repair service, collect as many machines as possible to "repair" and then vanish. Along with your equipment which is then repaired and resold. It`s not something you hear about every day, but these con artists do exist, so be aware.

How to Protect Yourself

The best way to ensure nothing bad happens to you and your laptop is to opt for a professional laptop repair service. They should be legit. Here are some signs that the service is a good one:

o They have a proper storefront or office.

o You need to sign a service agreement.

o Paperwork is filled out with information on both sides.

o They have high quality ads.

o People are recommending the laptop repair service.

None of these should be taken on their own as a sign of quality, but if you find a laptop repair service that fits 3 or more, chances are you have a good service on your hands. You might even ask to speak with previous clients to find out what their experience was. And, of course, there is always the internet, which can be very useful for finding reviews of the specific businesses, if needed. This can be a huge help in making a decision as to which service to use.

Your laptop is an important part of your life and as such, it should be cared for. Don`t just hand it off to anyone who claims to recognize a circuit board. Take the time to research laptop repair in Toronto and find the best repair service for your computer.

Ensure Quality With Cheap Laptops Available in the Market

Students very often seem to keep changing their widgets just to uphold the latest technologies or the latest trend. Normally, as it is students' nature to keep changing their laptops, like many other gadgets this category of consumers would definitely look for laptops at cheap prises. However, though this category of consumers looks for laptops that are cheaper they do not compromise with the quality or technologies of this gadget. Keeping this category of consumers in mind manufacturers ensure that they deliver their best to come up with laptops that are cheap but loaded with the latest mobile technologies. So, be sure to find one such laptop if you are planning to get a new one.

As a student, one should be concerned over the security of this widget as it is a valuable commodity. As such, students should be aware of the latest technology that ensures security for laptops. There are softwares available today that can recognise fingerprints and the face of the users. You can find the face recognition software in the latest Lenovo laptops which will help you recognise the person who uses your laptop in your absence. One should not be surprised that there are software that can trace the stolen laptop if a person uses it to access the Internet. It is the IP address in conjunction with the Internet that helps to trace the stolen laptop. A sound laptop cable lock can also give the students some security.

As it goes without saying that nobody can hardly tolerate the poor performance of a widget and it applies to laptop as well. These days the potential buyers can easily find cheap laptops that give performance up to the mark. So, as a wise shopper one should ensure the size of the hard drive, type of the central processing unit, range of the RAM etc. prior to actually owning one. Generally, the capacity of a laptop is 40 GB. However, being a student as you may have loads of data, mp3 files, videos etc. to be stored you may look for a 80 GB Hard Disk. The 256 MB RAM is no longer in fashion. Generally, 512 MB RAM is normal for students. However, pupils these days demand 512 MB RAM considering their heavy usage. It is not advisable for students pursuing professional courses to have a processor which is less than 2 Ghz. Processors call for more Ghz when there is heavy usage of it like heavy data transfer and management, graphic design etc. Students must also ensure that the cheap laptops that they have selected are as wireless as possible as they very often need to run from one class to the other in many of their institutions. Laptops are more or less wireless, but to be hassle-free ensure that your laptop has at least 802.11g wireless network. Laptops provide options like DVD writer, CD writer and CD-DVD reader which help the users in storing, transferring and reading data. Among them DVD is found to be a very good option as it gives immense backups and helps you make your personal DVDs.

Finally, to end up with cheap laptops, online shopping would be the most suitable option. It will simply make your shopping hassle free. Moreover, it helps you compare a brand with many other brands just sitting at your home. This also helps get you all the information regarding your select laptop in detail. In addition, the users can even find the best deal online shopping. However, before going for online shopping the potential shoppers may just visit a physical store to have the actual feeling of the laptop's size, weight and look.

Is WiMAX Secure?

WiMAX is the broadband wireless access system designed by the IEEE 802.16 committee for carrying high-speed communication over long distances. Telecommunications services and Internet has become more attractive due to WiMAX. The main purpose of WiMAX is to guard the service provider from thievery of service, and to defend the patron from unofficial information revelation. WiMAX networks vulnerable to man from bother, revealing user to a range of privacy and possible attacks

The use of 802.16e amendment provides strong support to confidential data due to AES cipher. WiMAX offer good intentions to several potential attacks such as Rogue Base Stations that that imitates a justifiable entrée point, DoS Attacks enable a computer source occupied to its intentional users, Man-in-the-Middle Attacks which formulates sovereign links with the fatalities, and Network exploitation with spoofed supervision frames. WiMAX security ropes two quality encryptions as DES3 and AES are the leading edge with DOCSIS BPI and security protocol. WiMAX use CCMP with AES for broadcast security and data veracity substantiation. The use of PKM Extensible verification relies on the TLS standard of public key encryption.

The authentication structure of WiMAX based on (IETF) force which supports user name, password, smart cads, and digital certificate containing public key and MAC address. The use of PKM which is a client server protocol performs like a client. You can secure your messages with AES, CMAS, and HMAC. WiMAX offer privacy, data integrity, authentification, authorization and access control. WiMAX security has different layers within a system with different aspects of security with redundant mechanisms for example the link layer used to prevent over-the-air eavesdropping, network layer provide various method for security, transport layer also called SSL provide security to transport layer protocols and packets, application layer deal with the digital signatures, certificates, and digital rights management etc, physical layer handled both uploading and downloading of channels.

WiMAX technology use PKM Protocol to gain approval and passage material from the BS to sustain episodic reauthorization. The X.509 digital certificates DES used to make safe key between (SS) and (BS). In physical layer subscriber station research for download signals from the base station and synchronize with it. WiMAX technology in real test by wide-scale network deployments because it is mostly in use where research work is going through and moreover attackers in abundant. The fuzzing protocol of WiMAX facilitate attackers to further influence BSs or SSs and then WiMAX security is inadequate to conjecture

Within WiMAX Encore Encryption

WiMax Encryption is the technique used to shelter the discretion of information sinuous between a spreader and a recipient. Encryption deals with the blockage of data to be protected also called encryption key. Encryption key used to achieve an overturned arithmetical process to produce a secret message or code text which is incomprehensible and therefore can be driven across the network without terror of being snooped. There are various kind of keys used for encryption and to handle it. The procedure of this is called asymmetrickeyencryption. The National Institute of Standards introduced AES specified as a link-layer encryption technique to be used in WiMAX. It is based on Rijndael algorithm that works on a 128-bit block size of data. The Rijndael algorithm organized in a 4 x 4 array of bytes called a state.

The size of encryption key sizes may be 128, 192, or 256 bits long and so on. These appealing chattels make counter mode an admired selection for AES accomplishment. AES have validation Code such as CBC-MAC and CBC-MAC are the protocol defined in RFC 3610. The power control diminishes the common power utilization of the CPE and the make possible the meddling with other base stations and for Non-Line-Of-Sight (NLOS) it is also intimately dependent relative on the authorization and fences.

There are lots of relative issue and characteristics of WiMax Encryption such as Error Detection Techniques used to reduce the system signals to noise ratio (SNR) by using interleaving algorithms, Convolutional Encoding, and Strong Reed Solomon FEC. They recover corrupted frames, fading, and Scanning & Synchronization deal with the downlink broadcast by perceiving the cyclic frame introductions, Uplink & downlink parameters detection throughout the DL-MAP and UL-MAP. They are the BS which can allocate admittance to the entity channels, Ranging & Subscriber Station enable processing .These are the part of framing and media access in 802.16 and consist of initial ranging and periodic ranging. This consists of the modulation and coding schemes holds by the SS within the WiMAX Frequency Division Duplexing. It support half-duplex or full-duplex

Subscribers station authentication and authorization & registration is the stage in which the SS must be authenticated by the BS and obtain authorization from the BS by using the PKM Protocol, IP Connectivity acquire an IP address through the DHCP protocol and get parameters from the BS. It is lithe structure formed by the IETF (RFC 3748), permit random and intricate authentication protocols to be swap between the requester and the authentication server. The protocols of WiMax Encryption are using a range of recommendations such as smart cards, certificates etc. The mostly used standard of WiMax Encryption is Remote Access Dial-In User Service also called RADIUS which is a client server User Datagram Protocol (UDP) application run over IP

Extend Your Laptop Autonomy - The Basics

Year after year, the performances of our laptops continue to make extraordinary leaps forward. The capacities of calculation and of storage evolve in a phenomenal manner. Yet the laptops autonomy while improving does not progress the same manner. In five years, average autonomy of our notebooks was multiplied by two. Despite these advances, the nomadic user wants more. Is it possible to extend the autonomy of his laptop? Which components do have the biggest influence on performances? What can you do to extend to extend your laptop autonomy?

In contrast to what one could sometime think, the battery builders do their best to maximize autonomy. It's a consistent fight in between autonomy progress and more energy demanding laptops. Despite the manufacturers' efforts, it is presently difficult to obtain autonomy any higher than four hours on a standard notebook. This value remains comparatively weak facing the current needs. It is therefore important to maximize all avenues to ensure that your laptop autonomy is at its best. To guide you in this venture, we will approach the different solutions of economy of energy. To start, we will enumerate the basic principles that it is important to respect. In other articles we will review other important elements tied to your laptop battery, how you can adjust Windows, special software and additional peripherals.

First things first, let's review some basic autonomy savers.

1) Make sure that your laptop doesn't overheat

When in use, the ventilation orifices must not be obstructed. An overheating would induce inevitably a growth of the electric consumption. If the laptop is old, it will be able to be wise to clean these gates. Remove papers and other items that maybe on the laptop keyboards (if you are using a separate keyboard). At last, note that to obtain an optimum autonomy, it will be necessary to avoid using or to store your laptop in a surrounding too cold (less than 45F/10°C) or too hot (more of 85F/35°C).

2) Use the right drivers, and to update them

As each knows it, to manage an interface (generally material) or a peripheral, an operating system needs a software called drivers. With a laptop, the usage of optimized drivers is particularly important. Without that, Windows could be incapable to manage the variable frequency of a processor (central processor or graphic processor) or all other method of economy of energy. To find recent drivers, go to the manufacturer website for your laptop.

3) Defragment your hard drive regularly

The fragmentation means that the data of a same file (a picture or a document text for example) find themselves disseminated to several places of a hard disc. At the time of the opening of a fragmented file, the head of reading of the disc will have therefore to do many movements to collect the "pieces" of shed files on the disc surface. This phenomenon induces an excess use of the hard drive that therefore decreases autonomy. To avoid this problem, think about to defragment your disc when your computer is plugged in to a power outlet.

4) Operating System updates

Operating systems bugs are consistently being fixed as well as improvements are being made. There are some well known cases were computers where affected by issues due to the OS. Therefore, as a general rule updating the operating system must not be neglected. Verify regularly that your operating system has the latest updates.

Buying a Laptop - A Quick Guide to Make the Right Choices

Looking for the best laptop for your home or business? If you want to have some of the basics facts before you start shopping, here a small guide of purchase of laptops.

Laptops have made some drastic progress in the last few years and at that point in time they can easily be a substitute to a desktop for most users (the only exceptions being programmers and heavy gamers). While the price of laptops is a little bit more than a desktop for most users even the cheaper laptops will suffice for their regular needs. The price starts around $299 and can go all the way to $3,000; you will find the majority of the laptops in the $600 to $1,000 range. We will review briefly what are the musts and also what to not waist your time and money on.

The processor

The processor is the heart of your laptop. It treats the instructions and the data before redistribute them.

There are two main competitors in that market INTEL and AMD. Every brand has multiple processors segmented in several families. Is one of the two brands better than the other? Unless you are an absolute gamer needing the latest and greatest and most powerful processor, the response is no. Whether you use an AMD Athlon(TM) 64 X2 dual-core processor or an Intel® Core(TM)2 Duo mobile processor, you won't really notice a difference. As both brands compete to improve their processors, every few months, one leads the other and then vice versa a few month later.

At the time you are ready to buy your laptop, check that you have one of the latest processors (something that came out in the last 12 months) and you will be all right.

The Random Access Memory (RAM)

Simply said, the more memory your laptop has, the faster and most stable your laptop will be. Count a minimum of 2GB to run Windows Vista and 1GB for Windows XP. If the laptop you are looking at has more, even better but it is not essential.

The hard drive

The hard drive stores your applications as well as your documents. The bigger your hard drive is, the more room you will have for your documents, photos and video. Keep in mind that external hard drives are available and will allow you to increase your storage capacity. Also, in case of breakdown, you will be well happy to be able to recover the part of your documents that was backed up. Accident happen to laptops, so it is definitely something worth looking into; many external hard drive can be purchased starting at $100 for 500 GB, that's plenty of space and a great insurance policy against losing precious pictures, documents...

As far as the capacity of the hard drive needed for your laptop, you need a minimum of 160 GB these days.

The graphic card

This is rarely something you are inquiring about at the time of a purchase and yet, it is a very important element of your laptop. In fact, as opposed to the classical PC, it is practically impossible to change the graphic card of a laptop. Once you have it, this is for life! (at least the one of your laptop). Graphic card such as the Intel X3100, nVidia 6100/7000 will suffice for a usage office, web surfing, video and photo. For gamers, look for nVidia GeForce 8600M or a ATI Radeon mobility HD 2600.

The screen

Most models have a 15.4 inches display with a resolution of 1280x800. This is sufficient for a regular use and even games. If you want an increased comfort, buy a laptop with a 17 inches screen (the keyboard will be bigger to). Latest trend, ultra portables and mobile computers with screens in between 9 inches and 13 inches which weigh less than 3 pounds for some of them; if your have a nomadic lifestyle, this is definitively something to consider.

The Connections

Few person pay attention to them and nevertheless, this is a crucial point. All the laptops have basic connections.

USB ports for peripherals such as the mouse, printer, webcam, MP3 player... In any events, two USB ports are not advisable. Three or four are definitively better. VGA port will allow you to link your laptop to monitor. HDMI for high video definition (blu-ray and HD DVD). S-video output is the analogical version of the a HDMI. You will find less and less of these connections FireWire or IEEE 1394 will allow you to connect to digital camcorders mp5 and mp3 at fast speed. SATA connection allows you to connect to a SATA external hard drive at fast pace. An Ethernet (RJ45) will allow you to connect to the internet. This connection is an absolute must. RJ11. This is to connect to a modem, not very useful nowadays The express Card allows you to connect to peripherals such as tuners The PCMCIA does the same function as the express card but it is less and less used these days.

As far as connections, look for four USB, VGA, HDMI, Ethernet connection, Bluetooth and an Express card. Integrated cameras are also a nice thing to have to communicate via applications such as Skype.

Fast and easy, you can of course gather a lot more information, but if you follow the guidelines above, you should buy the computer you need and not the one they are trying to market to you.

Tips to Maximise Notebook's Battery Life

Notebook batteries are designed specifically for different notebooks brand as well as models. Today notebooks are powered by lithium ion batteries. Lithium ion batteries are lighter, have a better power-to-weight ratio, can hold a charge longer, have a longer usable life, and do not have the memory effect to fail prematurely.

Lithium ion batteries are also inexpensive to manufacture as compared to the earlier generation of nickel metal hydride batteries. The only shortcoming about lithium ion batteries is as they contain lithium salt dissolved in a highly flammable solvent, there are chances of overhead which can result in short-circuits or even blow up in flames.

It is a common fact that all notebook batteries have provision for limited time of power supply. A good bargain is to check the battery power while buying a notebook. Here is one instant tip to optimize the battery settings in accordance with the energy saving mode of your notebook. These settings will put the hard disk into sleep mode whenever the workload is less and it will reduce the notebook microprocessor performance in order to maximize its battery life.

From the system preferences mode of your notebook, select view menu, then choose energy saver option from view menu. Right click on show details option and choose battery power from the pop-up menu. Finally choose longest battery life from the energy settings pop-up menu.

Tips to optimise your notebook batteries are described in the following:

It is better to keep your notebook on standby mode when not in use for certain amount of time. Standby mode ensures all current info is saved in RAM with minimum consumption of battery power.

It is a good investment to add more memory to your notebook as it saves battery power by reducing Windows' dependence on the virtual memory swap file on your hard disk.

Try to set the screen brightness of the LCD panel of your notebook to the lowest comfortable level as very bright screen tends to consume more power from your battery.

Charge your notebook battery frequently with a battery charger or AC adapter. It is very important to clean your battery's metal contacts every couple of months to make it dust free. You can use a cloth moistened with rubbing alcohol to clean your notebook battery.

Turn of the unused features and technologies of your notebook which are not frequently usable. For example, it is better to eject the CD or DVD when you are not using them as the optical drive has the tendency of reading CD or DVD it finds very often and this process consume extra battery power.

Similarly it is better to get rid of the outer peripherals such as printers or digital cameras as they can still draw power from your notebook battery even when they are not used.

Turning off or at least disabling the PC Cards, FireWire devices and USB when not in use also saves battery power. In fact, disabling modem, network cards and USB ports consumes less battery power even when they are on. These devices are easily disabled in device manager.

To save power, it is good idea to turn off the AirPort, Wi-Fi, IR radios and Bluetooth option when it is not required to use. Virus scan should be set only during the time you are usually plugged in as full-disk virus check by the hard drive and CPU consumes additional power from battery.

Opt for the power console applet to customize the power profiles on your notebook. Do not worry in case your notebook does not have power console applet option for most of the operating systems (starting from windows 98) have Power Options utility in Control Panel.

You can use power saver option of your operating system to adjust the CPU processing power. Optimum CPU processes consume additional battery power and hence should be avoided if not required. Stop the auto start applications on your notebook, so that your notebook`s CPU can be stopped from doing unnecessary work.

With the above mentioned handy tips, you can truly increase the battery performance of your notebook.

Coolest Laptop Cooling Part 1

It is amazing how many laptops/notebooks have ineffective heat dissipation in the case.  Poor laptop cooling is a top reason for system failures in my humble opinion. A computer system without good free flowing air circulation will have its hard drive, CPU, motherboard and battery life greatly reduced very quickly.

If you have had your computer for many years, it might need to be open up and have the dust cleaned out. A lot of dust will accumulate inside of your case after a period of time. Case and CPU fans will get so dusty that they will either slow down or stop working completely. The danger of overheating vital components will than become imminent. You might need some critical enhancements in air circulation to help your hardware stay cooler. A really good sign you need some better air flow in your computer case is when your fans are so noisy that you can not hear yourself think. Accumulated dust will make fans noisy and reduce vital air flow, causing overheating issues.  Your computer will actually slow down and start giving you strange performance issues and error messages when heat rises.

If your case and fans are practically dust free, than you might want to look at some good air movement devices out on the market. The more air circulation you have providing more cool airflow, the better your CPU and other hardware will run. It will also extend the life of your expensive computer.

There are some great ways to improve your laptop cooling.  You could turn your house or office air conditioner down to say a nice cool 50 (°F) or 60 (°F) degrees. But that would not be practical. Besides, not enough cool air would be push inside of your PC case to make that much difference.

What you might want to look into are some well made secondary fans for your notebook case. These electric fans are provided as external secondary cooling for your  notebook. They do not replace your existing components like your case fan, CPU fan or any motherboard heat sinks. They simply add extra cooler air to prevent computer hardware from overheating.

Hey, by the way did you know that the cooler your hardware runs the faster your system will run. It's true! The hotter your case and system hardware gets the slower it becomes. So look into some good air flow movement boosters before it is too late!

EEE PC 1000 Review - Pros and Cons

With the arrival of the EEE PC 1000H, the new ultra portable gets a bit more robust and comfortable than the previous 7 inches and 8.9 inches models. In the process, the EEE PC gains one pound and gets a bit more expensive.

Despite all the issues on the first models, the EEE ultraportables have been very successful, with more than seven million 7 inches units sold in between January and July 2008. Just as the 8.9 just hit the marketplace, the EEE PC 1000H is being launched and wants to attract more customers interested in the ultraporatble concept but may be resisting letting go of a full laptop..

One of the strong points is the new slick design and of course the new 10 inches screen. Not only this new dimension improves the reading comfort, but it also allows the Asus to have a worthy keyboard.

New ultraportable, new processor; faithful to Intel (Celeron equipped the 7 and the 9 series) Asus integrates the latest processor from the Californian brand, the awaited Atom. This low consumption processor should, on one hand, improve the performances but also, improve machine autonomy. This point is important since on the previous models, the batteries where very small for various reasons (weight, cost..) therefore, the autonomy of theses machines suffered quite a bit, which takes away a big part of their interest. It is anticipated that due to the very low power consumption of this new processor and therefore the added autonomy, a new wave of interest shows up for Asus models and for the other ultraportable in general.

The screen has a resolution of 1024 x 600; this is definitively a plus as the screen is about as good as some of high end 11 inches ultraportables. With the bigger screen, better and bigger keyboard and an autonomy expected around 4h30, the EEE PC 1000 and his price of $600 is going to be a formidable competitor for other ultra portables, some of them reaching prices up to $3,000.

The downside of this new model is the weight. It went from less than two pounds on previous models to 3 pounds now. Some "ultranomades" will probably not appreciate. If weight is a definite issue for you, the planned arrival of the EEE PC 904 and 905 should take care of that issue, as they will have weight right around two pounds.

The EEE PC 1000H is delivered with Windows and a version Linux is also available. The hard drive has a capacity of 80 GB, one GB of RAM, of 3 USB ports, Bluetooth, Wi-Fi a Webcam and of a microphone.

Pros: - Bigger screen - more comfortable Keyboard - improved Autonomy

Cons: - Heavier

Building on its previous success the EEE PC 1000H should do well. At that size it's getting a little bit away from the ultraportable attribute that made is reputation, on the other hand, it is a more comfortable user experience... All in all it's a very good machine that will attract customers that want the ultra portability while keeping a certain level of workability.

How to Secure Your Laptop

Laptops are becoming more and more popular as they replace the standard desktop computer. Falling prices and technological improvements will make laptop sales outrank desktop sales for the first time in 2008. But as the numbers in laptop sales grow numbers of notebook theft also increase dramatically. This article tries to show you ways to keep your laptop safe from theft.

1. Notebook Computer Lock: A notebook computer lock works similar to a bicycle lock. You attach one end of the lock to your laptop and warp the cord around a fixed piece of furniture. All laptops provide a slot for notebook computer locks. One of the most common is the Kensington slot. In most cases it is located at the side of your laptop and marked with a small lock sign. Other types of locks fit directly into the VGA port of your machine. Find out which kind of notebook computer lock suits you best.

2. Laptop Alarms: Now that your laptop is physically secured with a notebook computer lock you should make it theft-proof on the software side. There are lots of programs out there that transform your machine into a fully-blown alarm system. Your computer already has speakers why not use them against possible thieves. Some programs use your laptop's built-in motion detector to know when your notebook is moved. Others blare your gadget's horns when the power cord or a USB device is unplugged. A handy tip for library visitors is to mount a library DVD or CD into your drive. When a thief tries to escape with your laptop the library's security gates notice the disc an sound the alarm.

3. Retrieval: There are great programs out who can detect the IP address of your stolen laptop and show it on a Google map. Those programs can also delete sensitive data on your machine the moment the thief logs onto the internet. Software like this can be you last guard against identity theft if your machine is already stolen.

In my opinion securing your laptop on the software side is a great way to keep your data and identity safe. But first and foremost you have to secure your machine physically. A notebook computer lock really is essential for everyone who wants to keep his laptop and data on the safe side.

Notebook Computer Displays

When it comes to laptop computers, the choice of display size is one of the most important considerations you have to make. It is just as important as ram size, hard drive size, and processor speed. The display size will also heavily factor into the overall weight of the notebook computer. A larger display size means a larger physical footprint, which is more or less desirable depending on whether you need an ultraportable, mainstream, or gaming style computer. The most important factor, however, is your comfort level. A smaller screen (ultraportable size) may mean great mobility, but none of that is helpful if text or pictures appear uncomfortably small.

Types Of Displays

Due to increasing demand, more and more manufacturers are making widescreen displays available as well as standard displays. Standard TV's and computer displays utilize a 4:3 (or 1.33:1) aspect ratio, including notebook computers.

Standard 4:3 Aspect Ratio

The standard 4:3 aspect ratio has been in use by notebook computer displays for a long time and is offered in several screen resolutions:

- 800 x 600 (SVGA) - 1024 x 768(XGA) - 1400 x 1050 (SXGA+) - 1600 x 1200 (UXGA)

Resolutions higher than 1024 x 768 can only be found in displays sized 14 inches and above. Ultraportable notebooks with displays sizes under 14 inches are unable to have high-resolution displays.

Widescreen Display

Using a 16:9 or 16:10 aspect ratio, widescreen displays can generally display about 25% more content than a standard display. Computer manufacturers offer several size displays from 8.9", 10.6", 11.1", 12.1", 13.3", 14", 15.4", to 17". These sizes are popular now with even larger sizes in the pipeline.

When used for entertainment, DVD movies in particular, a widescreen display is in its element as it shows widescreen movies in their intended 16:9 aspect ratio. This means a bigger picture, more comfort and thinner or no black bands on either side of the picture.

The widescreen display also makes it easier to edit and view panoramic images and may eliminate horizontal scrolling on your computer altogether. When editing images of normal 4:3 aspect ratio, you can simply place your GUI tools/utilities in the unused spaces on either side of an image. In any case, a widescreen display can help you increase work and play efficiency.

Another benefit of the widescreen display is evident when it comes to serious work - the ability to display two windows side by side and to drag and drop (or copy n' paste) data without having to switch windows is invaluable.

Common Widescreen Display Resolutions

Here are the common resolutions found in :

1280 x 768 And 1280 x 800

1280 x 768 (16:9.5) and 1280 x 800 (16:10) are the two most common resolutions used in 10.6, 12.1, 13.3, 14, and 15.4-inch entry-level widescreen notebook computers. They provide about a 25% more onscreen content than standard screens with 1024 x 768 resolution.

1366 x 768

This resolution provides a 16:9 aspect ratio and a great widescreen DVD movie experience without any black bands above and below the picture.

1440 x 900

This resolution 16:10 is found only in 17" notebooks and is positioned as entry level in 17" widescreen notebooks.

1680 x 1050

This is currently the mainstream resolution, also 16:10, for 17" widescreen notebook computer displays. There is a 35% increase in onscreen content compared to normal 17" screens using a standard display resolution of 1280 x 1024.

1920 x 1200

At this time this is the highest for 17" widescreen notebook displays, and provides a 75% increase in onscreen content when compared to a standard 17" screen of 1280 x 1024 resolution. A great display for movies and gaming, however this relatively heavy laptop computer has tradeoffs in mobility.

How To Find The Perfect PDA For Your Computing And Communication Needs

When you decide to get a PDA, there are so many choices it is difficult to decide on one that is right for you. The most important consideration is to know how you are going to use the PDA once you have it. Take time to think about the possibilities before you make your purchase.

Some people simply use their PDAs for a clock and calendar, address book, and to take a few notes. If this is the case, you probably do not need a PDA with a lot of memory. PDA memory starts at 16 megabytes, two-thirds of which will be available for use after accounting for the operating system.

If you use the PDA for accessing the Internet, making and writing on spreadsheets, or playing computer games, you will need more memory. Some PDAs have a Global Positioning System (GPS), while many of the newer ones double as mobile phones. All this takes as much memory as you can get on a PDA.

Processing speed may also be important to you. If you need to access the information in your PDA and you do not want to wait, you need a fast processing speed to get it done quickly. Check out all the options and find the one that will work for you.

You can buy software or download it from the Internet to personalize it further. Also, you might want a PDA with special features like a memory card slot. You can get PDAs with synchronization so that they can give and receive data to and from your PC. It is sometimes difficult to type in information on a touch screen with a stylus. Synchronization makes it much easier to get some data from your memory card onto your PDA.

Memory cards are very important to most PDA users. These are used to save and transfer data from their PDA to other devices such as PCs. Remember that there are memory cards with many different amounts of storage space on them. Be sure to get one that is adequate for the information, pictures, or MP3s you want to store on them.

Bluetooth technology is popular these days, and many PDAs come with Blue-tooth-enabled devices. You can get headsets, mice, and keyboards that will work with your PDA. These accessories can make working with your PDA much easier.

If you are visually impaired, there are PDAs made for you. These PDAs do not rely on touch screens for input. Instead, they are controlled by voice commands and buttons that make the programs easier for you to use.

As you are getting your PDA, remember to get those items that will protect it. You will need a case for your PDA, but make it one that will not weigh it down excessively. It should be sturdy, but not too heavy. Then, get electronic cleaning wipes. These are invaluable in cleaning your touch screen without damaging it.

Getting the right PDA for you can take a little research and some time spent shopping. If you find a PDA you are satisfied with, the effort will be worth it.

The Freedom of Printing With the Bluetooth Wireless Printer Adapter

Belkin is a manufacturer that is quite well known for routers, cables, and other networking components, and offer great value for the price. They operate under the slogan, "Connecting people with technology," which seems very appropriate for a company that provides so many networking solutions to the masses. One of their latest products is their Bluetooth wireless printer adapter.

The Bluetooth enabled wireless printer adapter that is being offered by Belkin, is one of their latest entries into the market of wireless technology networking accessories. With the way that the world of networking for this technology is heading and with such innovative product from Belkin, some are saying that their future slogan will be "Connecting people with wireless technology."

They offer the Belkin F8T031 Bluetooth Wireless USB Printer Adapter so that you can print directly to your USB printer from any wireless Bluetooth PDA or computer that is Bluetooth enabled. The Belkin Bluetooth wireless printer adapter is fast and works seamlessly, providing much needed convenience when it is time to print.

A CD is also provided with the adapter, which has a printing utility that lets you print from your Palm OS or your Pocket PC device. In addition, it supports printing functions in virtually all versions of the Windows OS, but it will not work with Apple Mac computers.

The Popularity of Bluetooth Wireless Networking is Growing

Bluetooth wireless networking is a technology that is sweeping the globe and being integrated into a wide variety of electronic devices these days. The underlying Bluetooth technology was developed in the mid 1990s and began to be seen in more and more pieces of equipment toward the end of the decade.

The developers of Bluetooth, Ericsson (which has since become Sony Ericsson), endeavored to create a single standard for wireless technology networking that could be easily and inexpensively integrated into various electronic devices for ease of connectivity. Having a single standard shared by all electronic developers, designers and manufacturers was the ideal because it would allow the end user to enjoy wireless networking of their devices, regardless of who manufactured the electronic item.

Ericsson made a strategically brilliant decision in the early days of Bluetooth wireless networking technology. They decided to make the Bluetooth specifications available free of charge to companies that were interested in developing and implanting the technology into their products. This created a spirit of cooperation amongst the developers.

This has helped to make this technology very affordable for companies to continue to develop innovative products using the latest technology platform. This has also made its networking to quickly become the standard in mobile wireless technology, and has made the devices more affordable for the end user as well.

With wireless networking technology functioning in different devices, these electronic tools and gadgets are able to seamlessly connect with each other and communicate and transfer both voice and data simultaneously. The Bluetooth wireless technology provides for three different kinds of defined communication ranges.

The Class 1 devices are the most powerful and have a range of up to 300 feet. Class 2 devices are of lesser power and provide an effective range of 50 to 100 feet. The Class 3 devices require even less power and their range is limited to approximately 15 to 30 feet.

One thing many people fail to recognize is that this latest technology was never designed to provide for anything other than short-range connectivity and communications. And, this short-range limitation is actually a benefit that was intentionally designed into the specifications.

The first benefit of the short-range design of its networking is that this factor limits the possibility of interference from devices belonging to others who are in close proximity. This keeps others from connecting with your devices and is a form of basic security intended to protect your devices and your data.

Another benefit of limiting the range of networking devices is that less power is required for the transmission over shorter distances. This in turn means that you can enjoy longer battery life, and since the majority of its enabled products are powered by battery, this is an important feature for most users.

There are a multitude of electronic devices that use Bluetooth wireless networking standards, such as: the Bluetooth wireless PDA, the Bluetooth wireless phone and the Bluetooth wireless headset than works in conjunction with them, the Bluetooth wireless printer, the Bluetooth wireless stereo headset, just to mention a few. Bluetooth technology is increasingly in demand in a wider range of products and manufacturers are working hard to satisfy this demand with more Bluetooth enabled electronic devices.

Laptop Carry Cases - Keep Your Laptops Safe and Secured While On the Move

Gone are the days when one could have access to computers only in his office, home or cyber cafes. Thanks to the advances in mobile computing technology, many portable and compact computers have now been developed by the researchers. These computers are called laptop computers or simply laptops. As these devices are often carried by people with them, it is very important that they should be placed in a safe and secured carry case. A large variety of such laptop bags are now widely available in the markets around the world.

A laptop carry case helps in keeping one's laptop safe and secured while she or he is on the move. Manufactures have rolled out a number of good looking and robust laptop bags in the markets these days. These carry cases are made up of a water resistant material and they also generally have padded compartments. Such compartments help in preventing damages to the devices due to accidental jerks and shocks. Some varieties of carry cases could also be equipped with a hidden telescopic handle. Still others may have internal and external compartments for keeping diskettes, binders and lose files.

Some laptop bags may also have compartments for keeping business cards, pens and some stationery. Many of them come with an integrated lock system, quick release straps and an ergonomic carrying handle. Some manufacturers have released laptop bags that have a customisable internal fit and are made up of a high impact polypropylene material. Many cheap laptop bags are also available in the markets. Such carry cases generally do not have extra compartments for keeping other items along with a laptop.

A range of rugged, light weight and stylish looking laptops carry cases are available to consumers at markets in the UK and other parts of the world. Most of them have a contemporary design that would appeal to a fashion conscious consumer. A good quality laptop bag is a must for anyone who carries a laptop bag with him or her.

Is Bluetooth On A Collision Course With Wi-Fi?

The recent appearance of some "Wi-Fi" mobile phones on the market has many folks wondering "what could be". With regards to Bluetooth vs WiFi phones are we seeing a potential collision of capabilities? Not so fast...don't be blinded by the light.

OK, you may have seen a couple of mobile phones with Wi-Fi on the market lately... and it appears that the penetration of these mobile "Wi-Fi" phones is only going to increase with time. It also seems that what the current user can achieve with Bluetooth... may also be possible via Wi-Fi at some time in the not too distant future.

Below I've listed the primary use cases for Bluetooth and how Wi-Fi "may" offer a solution.

1. Wireless headset - Wi-Fi headsets take up a lot more current than Bluetooth, this doesn't seem to be insurmountable in due time though.

2. Wireless data transfer - Already possible via Wi-Fi

3. Security - Bluetooth's frequency-hopping transmissions ensure security and less interference, but this again is not an insurmountable hurdle for Wi-Fi

4. Mobile to PC Sync - Possible via Wi-Fi

If a manufacturer is paying $X per chip to put Wi-Fi in... they might as well work towards solving these problems and remove BT from phones.

However, in my honest opinion there's more to the story if you really look under the hood.

So, I believe rather than competing, the two are coming together.

Bluetooth will probably always remain in the handset for two reasons. The first is that it enables low power headsets. Unlike Wi-Fi, Bluetooth enables synchronous voice transmission without the need for VoIP. It was one of the key requirements for the Bluetooth specification and means that headsets can be made that give a good talk time with small batteries. The overhead of VoIP processing for any standard that does not support native voice means that Wi-Fi is unlikely to ever take this market away. And despite the publicity of Wi-Fi in handsets, the only wireless connections that most people ever make is to a headset.

What will reinforce the continuation of Bluetooth in handsets is the new low power variant, also known as Wibree or Ultra Low Power Bluetooth. This is exciting the handset vendors because of its ability to connect the handset to a new range of accessories, such as watches, sports equipment and health sensors. This technology resides inside the same Bluetooth chip, so will add functionality to the handset for no additional cost.

The other important thing to realise about Bluetooth and Wi-Fi is their different topologies. Wi-Fi usually talks to access points, whereas Bluetooth devices talk to other Bluetooth devices in what is know as an ad-hoc connection. 802.11 - the standard behind Wi-Fi can in theory cope with ad-hoc connections, but it's a feature that is poorly implemented and lacks interoperability. Much of the power of Bluetooth has been in building the higher level stacks that provide the ability to find other devices, connect to them securely and perform a range of data transfers. It's taken Bluetooth the best part of ten years to get this aspect right. Wi-Fi hasn't yet started on it.

That's why there is now work going on to combine Bluetooth and Wi-Fi, so that Bluetooth is used for this initial setup of the connection, and then Wi-Fi is switched on, under the control of Bluetooth, to perform a higher speed transfer. There are potential issues to this approach, as both use the same frequencies and if the two are being heavily used at the same time, there may be performance issues that are apparent to the user. To combat that, handset and equipment vendors are also working hard on a combination of UWB and Bluetooth. This provides better immunity to interference, higher data rates at short ranges and a much lower power consumption that can be achieved for a similar data rate using Wi-Fi.

The reality is that we will probably end up with three short range wireless standard in cellphones in the next few years - Bluetooth (including Ultra Low Power), Wi-Fi and UWB. In the near term it's likely that Bluetooth and Wi-Fi will coalesce into a single chip, with UWB as an additional RF chip. If they're all controlled by Bluetooth, the good news is that the user will only have to deal with one application interface.

Laptop Is Better Than PDA

Talking about PDA and laptop is always interesting. Which one will become your friend in your journey? Depend on your needs, right? A PDA is a better portable and lighter hardware than laptop. If you need to do some important things but you need a simpler tool, PDA is your friend. But PDA couldn't do as many things as laptop. If you need to play some light games (or even heavy ones), laptop is the only choice for you (when you are outside your home sweet home).

Beside of this, laptop always has better specification. Some softwares won't work properly in your PDA (especially Adobe softwares because they need good memory). So if you think PDA is a better choice than laptop, think twice. Laptop has many extra features that you won't get in PDA. If you prefer larger monitor size, laptop is the winner once again. Do not forget that reading small fonts in PDA sometimes can be really annoying. For better internet browsing and word processing experiences, laptop has proved its worth.

But it doesn't mean PDA is not popular. PDA is a matter of speed. If you need to work faster, PDA is absolutely better. Laptop has bigger space, better specification, can do many more things, but about speed, PDA is still better. Some of us only care about effectiveness, that's why PDA is still popular (in fact, it's getting more and more popular).

Actually, I prefer to buy a high-tech laptop than to buy a PDA. Yes, the differences between PDA and laptop are not big nowadays because laptops are smaller now and PDA has stronger performance. But for what reason you buy a powerful PDA? If you want to play games (especially heavy ones like HALO 3 or CoD 4), of course a bigger monitor is better. I think at least a 17" monitor is needed to get the best experience. A heavier laptop is okay. In fact, your hand will be stronger if you carry a heavy laptop everywhere. Consider it as an exercise.

Does The Blackberry Help Or Hurt Work-Life Balance?

Does being constantly connected mean that you are constantly available to work, and does the Blackberry help or hurt the balance between your home life and your job?

It is a very common argument that having a Blackberry, Treo, or other portable device gives busy people more flexibility and enables them to spend time with their families they otherwise would not be able to. They are able to take vacations, can attend events, and run errands that being connected makes possible.

The CEO of RIM puts it like this: "Would you rather have your parents 20% not there or 100% not there?".

It is an interesting argument - does the cost of having people be able to reach you 24/7 make up for the benefits it provides? In fact, a survey by Korn/Ferris says that although 4 out of 5 business executives are always connected to work through PDAs, 77% of those say that it improves their work life balance as it allows them to leave the office earlier.

There are signs, however, that the scales are tipping too far to one side. Some parents say that "Blackberry" is one of their children's early words, and toy PDAs are available for kids "just like mom and dad!".

A recent AOL survey found some interesting stats:

Email user on portable devices has nearly doubled since 2004 59% of those with portable devices use them to check email every time a new message arrives 43% of email users with a device say they keep it nearby to listen for incoming mail while they sleep 83% of email users admit to checking their mail at least once a day while on vacation 53% of portable device users admit emailing from the bathroom, 37% check it while they drive (yikes), and 12% check email in church

I don't believe there is an easy answer to the question "does the Blackberry help or hurt work-life balance?", but perhaps it is best to keep in mind a postcard I read about online: "Your Blackberry can't love you back".

Cost Effective Laptops

One or another novel idea keeps on coming in hardware manufacturing. Due to the marketplace competition production cost comes down. Over the last couple of years laptop prices have fallen vastly. Now anyone can afford a good quality laptop which is cost effective. In addition, new technology comes very quickly, making high quality laptops outdated.

Laptops are becoming more advanced and powerful and also smaller. They are available in cheap prices also. The performance gap between a desktop computer and a laptop is narrowing day by day. The lowest priced laptops are now capable of handling most of the computer applications. They are coming with powerful speakers also.

Various kinds of laptops can be purchased. Ultra-Mobile PCs which are small in size and portable. Ultra portables are fitted with LCD screen of about 12 inches or less, weighing approximately 3 to 5 pounds. Thin-and-light Laptops generally weigh about 4 to 6 pounds having a screen size of 12 to 14 inches. Whereas, mainstream Laptops have a screen size of about 14.1 inches to 15.4 inches and weigh about 5 to 7 pounds.

Portability, Screen size, Price, Speed, Memory, Upgradeability, Hard drives, Batteries and Hardware are some of the parameters before buying laptops. Laptops come in the screen resolution of 1024 x 768 XGA or 1280 x 1024 SXGA. Laptops come in memory capacities of 128MB, 256MB, 512MB or 1GB of RAM.

Leading manufacturers launch new versions every year. Some of the latest laptops available in the market are Gateway NX850XL, Toshiba Qosmio G35, Toshiba Satellite M65, Sony VAIO VGN-TX670P, HP Compaq Presario V5000Z, Dell XPS M170, ThinkPad T60, HP Compaq nx6110, MacBook Pro, and ThinkPad X41 Tablet. There are various mid-size, cheap price laptops with fine multimedia support, double-layer DVD burner, advance speakers, mobile performance, and long battery life.

Every major manufacturer of laptops, like Dell, HP, Compaq, Gateway, and IBM have their lower end and intermediate models without compromising on speed and quality.

Online stores are offering various categories of laptops. Every model of a particular company can be compared in technology and price and best deals can be grabbed. Some stores are offering free gifts and accessories with cheap laptops.

The Benefits of the Bluetooth Wireless USB Adapter

Bluetooth mobile wireless technology is the clear and simple choice when you need convenient, short-range connectivity and communication between various electronic devices, and all without the hassle of a web of wires and cables. Bluetooth technology is a standard that is globally available and simple to use because driver software does not need to be installed. The Bluetooth wireless USB adapter is making the benefits of Bluetooth technology available to almost any device that has a USB port.

There is a wide array of products that are becoming available on the market that use the Bluetooth wireless technology networking, such as: cellular phones, laptop computers, a wireless technology PDA, a wireless stereo headset, hand-held computers, cell phone headsets and MP3 players. These are just some of the products that commonly have this technology integrated into them and more are being introduced on the market all the time. An enabled USB adapter allows you to add mobile wireless technology to a desktop computer or a laptop computer, that is not equipped with Bluetooth capabilities.

Once you add a Bluetooth wireless USB adapter to your non-Bluetooth computer, you will then have the capability of the wireless technology networking aspects of Bluetooth. This will allow your computer to wirelessly connect, communicate and interact with the other Bluetooth enabled electronic devices that you own.

The enabled USB adapters of this technology are specifically designed to plug directly into any available Universal Serial Bus (USB) port that is built into your laptop computer or your desktop PC. This enables your computer to be able to make short-range connections to its other devices.

The typical range of the USB adapter is approximately 300 feet. However, the range will be affected by a number of things and the effective range could be less. Things such as terrain, the general environment, the number of other people or devices connecting, and local interference sources can all reduce the actual range of the network of this technology.

A Bluetooth enabled wireless USB adapter communicates with its other devices by means of radio transmission over a radio band frequency which is not licensed. Over this type of short-range wireless technology networking setup, voice transmissions and data transmissions can be done simultaneously and they are virtually instantaneous.

This also ensures that transmissions have protection from interference of most types and that data transfers are secure. This helps in the sharing and accessing of data and information in a timely manner that is simple and easy to use.

One of the best benefits about adding Bluetooth technology to your computer with a Bluetooth wireless USB adapter, is that you can move away from all the wires and cables that are such a part of technology today. But, even though many devices will still need a power cord, at the very least to be recharged, the mobile wireless technology that is so simple to implement, thanks to Bluetooth, will at least eliminate some of the cords and wires that can be such a nightmare to manage.

Directional Wi-Fi Antenna

There are many different types of wireless antennas and one of the most underused is the directional wi-fi antenna. It will be used for shooting a wireless signal down a hall way or creating a point-to-point link. Directional wi-fi antennas can be directional such as a panel antenna or semi-directional like a yagi antenna and even highly directional like a grid antenna.

It should be used in areas where you need to cover like a 60 degree horizontal zone. This provides you with two benefits, first you are focusing your wireless signal in the area that you need it and two, this will increase your security because half of you signal is not going out of your building. Omni-directional antennas emit signals in a circle pattern with usually half of your signal leaving the building. If you signal isn't out side your area of operations then you won't have war drivers knocking at your dooor.

Yagi antennas narrow your beam even more; this can be used for short distance point to point links or to blast through obstacles. Point to point links can be buildings that are a couple blocks apart or in a smaller campus environment like a campus. Use Yagi antennas if you have some links that need to get through some sort of obstacles like trees or thin walls.

Highly directional antennas serve one purpose and that is to provide point-to-point links at longer distances. Grid antennas are very popular for point-to-point links because the perforations let the wind go through it. IF they didn't have the perforations then every time the wind blew the directional antenna would mover causing the link to drop.

If you are setting a up home and or small to medium business you should focus on using directional antennas. They will save you money and give you a more secure network.

Ubuntu Wireless

Using Ubuntu 7.10 to connect to wireless networks has been great. Linux for many years has only been for the geeks. I truly feel that the only thing that was holding linux back was the problems with installing Linux on laptops. You either had problems with screen resolution, your touch pad and or your wireless network card. The only people who could get the wireless portion of Linux to work would need to have command line skills and be able to either program the driver you self your find one in some obscure website forum. Then after many hours of work the wireless adapter would be active but they could only then connect to WEP encrypted networks not WPA of WPA2.

Now with Ubuntu 7.10, I installed it on three different laptop models with great success. Screen resolution, touch pad and the card were all functioning by almost default. Activating the wireless card took one extra step but Ubuntu prompted me automatically on how to install the drivers asking to enable the third party restricted drivers. There was no command line needed and no searching obscure forums for bad advice.

Linux is great but Ubuntu wireless is just awesome. I had Unbutu installed and running in under 15 minutes. That means drivers, and default apps with me connected to a wireless network. If you install Windows xp or Windows Vista you will need 30 minutes for it to load the base operating system then you will need to find all the drivers and then install you basic apps, hello two hours later you might me ready to work. 15 minutes or 2 or more hours you make the call.

After you get your Ubuntu 7.10 connected to your wireless network you can have access to all the thousands of free applications that the Linux community has put together. I don't know how many people who I ran into that say that the only reason they didn't like Linux is because it didn't run on their laptop correctly. Don't wait Ubuntu 7.10 runs great and will connect to your network by default.

Firstly, identify the reasons for getting a used laptop. Getting a laptop cheap is good, but not if you end up with a lemon. If you know someone who is a laptop expert ask them for advice when you're hunting for one. Ascertain the features you would like your laptop to have. Your budget for the laptop is also important. Consult the dealer about the warranty, technical support and service plans which come along with a used laptop. Checking the grade of the laptop is essential. Mostly laptops are 'A' grade.

So who do you buy a used laptop from? Resellers of laptops are great sources as they deal in buying and selling of laptops. With their contact information readily available, they receive a lot of feedback which can help you decide. Also resellers of laptops may charge you a little more but you can be assured of a clean operating system, devoid of Trojan horses or any other spy ware. They can also answer your concerns better than individual sellers. Individuals may sell a used laptop at a cheaper rate, but may not clean the operating software on it. Also their knowledge regarding their laptop will be limited and they may not be able to answer your questions satisfactorily.

Buying from manufacturers can assure you you're getting a great offer as they often get laptops returned by customers or stock those that have been refurbished back to their original condition. Dell for example offers laptops returned by buyers, refurbished ones and those which may have a few physical damages but are in working condition. Apple offers refurbished laptops as well with extended warranties if you opt for it.

See that your used laptop and computer have the same operating system, so as to enhance your connectivity experience. Conducting a few easy tests on the used laptop will make sure it's not a lemon before you reach home with it. Start with the make and model and see the technical aspects provided by the dealer and determine if they are similar. The ability to upgrade is important as well. Establish the Operating System and what antivirus works on it. Find out if there are any free RAM slots available. Find out the size of the RAM and if more can be added. Ask the limit that the Hard drive can support the Motherboard.

Other essential functions to check are if the CD, floppy drive and DVD writer work. Find out how much charge does the battery carry because if it doesn't hold for long you can ask for a further discount. Check for the power cable and if the transformer is in working condition. Ask for the original System Recovery CDS or any application CDS which came with the original purchase so that if you ever have to re-format the laptop you have them ready.

Do You Understand the Bluetooth Technology?

With every passing month, it seems that more electronic devices are touted as being Bluetooth enabled. And, while many people are excited about the advent of its new products, others are left scratching their heads wondering, "What is Bluetooth?"

Bluetooth mobile wireless technology has become one of the leading technologies for wireless communication world wide. The reason it has become so popular around the globe, in just a few short years since its introduction, is because it allows phones, computers, PDAs and other electronic devices to easily communicate with the other enabled devices nearby. The range of its networking is limited to a short range of about 30 feet.

Bluetooth utilizes radio waves, in the non-licensed range of 2.4 Gigahertz. This system has been designed with the intention of providing a secure and an inexpensive way to connect with and exchange information between other devices alike, all without the need of wires.

What is Bluetooth technology mainly used for? The Bluetooth mobile wireless technology has quickly become the standard for all wireless methods of communication. It can now be found integrated into the latest and most popular models of handheld computers, laptops, PDAs, printers and headsets, not to mention cellular phones. Manufacturers are finding more and more products to add the technology to, as the demand for this enhancement increases.

In addition to the Bluetooth wireless phone models, which are probably the most prevalent type of devices on the market, you can now also find its headphones and speakers. It is expected that other Bluetooth wireless audio and video products will continue to be brought to the marketplace.

With this type of advancement, it is conceivable that some day the only wires you will need to tame, will be the power cords that some of these devices will need for their power supply. That would be a welcomed change from the tangles of cords and wires that are common in home offices and entertainment areas.

One of the best features, is that all its enabled devices function on a standard protocol. This means that all transmission of data and voice signals between two of its devices, even if they are produced by different manufacturers, is straightforward and simple to implement.

It was the need for a standardized communication convention that prompted the development of Bluetooth technology. Rather than the need for each manufacturer to establish their own standards, and thereby limit the connectivity to other devices made by the same company, they can simply implement the Bluetooth wireless technology networking standard. This simple approach has made it a global solution used by all manufacturers and benefiting the end-user significantly.

Some of the other advantages of Bluetooth are: data transfers that are fast; communication with other devices alike that are not in a direct line of sight (as required by the infra-red protocol); inexpensive circuitry and components; the ability to transmit both data and voice concurrently.

This technology has been on the market for almost a decade. One of the reasons it is relatively inexpensive and widely used is because the original developer, Ericsson, has made the specifications royalty-free so manufacturers do not have to pay to implement the technology in their devices. Because of this, the use of Bluetooth technology is expected to expand and soon no one will be left asking the question, "What is Bluetooth?"

Your Bluetooth Questions Answered

Bluetooth technology has changed how cell phone users communicate. Those distinctive ear pieces are not just an accessory. It allows cellular users to talk using a hands-free device. But there is probably more to it than you might realize.

For example: did you know that at one time it was considered for wireless Internet instead of Wi-Fi? Many states are considering passing laws requiring all cell phone users to use hands-free devices while driving so to reduce the amount of distractions from trying to drive and talk at the same time. Do you have more questions regarding Bluetooth services? In this article we will address some of the basic questions and concerns regarding Bluetooth Technology.

How does it work?

Bluetooth technology works in the same manner as your laptop does when you are utilizing wireless internet. A signal is transmitted and then received by the other device. The signal is sent in packets of information.

The signal is recognized by what is termed "protocols." Most devices utilize at least one set of standard protocols to allow other devices, not of the same manufacturer, to communicate. There are some however that do not use the same protocols so there can be problems when the device tries to communicate.

What providers offer Bluetooth services on their phones?

A cell phone provider is not the one that ensures that the phone has Bluetooth capabilities. It is not an added feature like a data plan or text messaging. Its technology comes from the actual device itself. If you want to be able to use a hands-free device you must check the features on each individual phone model.

Can Bluetooth be used for anything besides making or receiving phone calls?

Its technology has many different uses. You can send ring tones to another phone, or you can send any type of information. The technology is very similar to that of wireless internet service.

Are some cars built with Bluetooth technology already installed?

Automotive manufacturers have long been working with it in order to offer the feature of having a car with a built in Bluetooth system. The first cars rolled off the market in the United States in 2004. In Europe the technology in cars has become far more popular.

The convenience of having it built into the car and having it able to sync up with your cell phone has proved tremendously valuable. As the technology becomes more integrated, the ease of use will increase.

How Android Will Change The Mobile World

In 2007 we had great announcements on the mobile phone field. First with Apple releasing the Iphone, then OpenMoko with the Neo 1973 and finally Google with a new open source platform called Android. From all the facts stated above, Android is the one shaking the open source community and also all the communication market. First let me explain how all this Google's OS thing started. Back in July 2005, Google acquired Android Inc a small company located in Palo Alto which created applications for mobile phones. From that day, speculations about Google getting in the mobile arena started. However nothing was done about Android until late 2007 and the question is, why did it take so long for Google do something about it.

The BBC spread rumours that the giant Internet Search Company initially wanted to reinforce their online applications aiming mobiles like Google Maps and Google Calendar, and were trying hard to deliver that.

Now if you stop to think about it, this makes a lot of sense as most of these mobile applications released by Google will cover all the needs and with little detail- they are free.

Google My Location will be replacing the GPS, cutting those extra costs that people pay to have this service. Gmail is free and Outlook will be no longer necessary.

Despite that, Google set a $10 million challenge which developers from the whole world will help to create new applications for the OS.

These are not the only changes that Android is bringing to the table. Now consumers will also be affected by the new OS; as it can be fitted to any device, the research to buy a new handset might be harder than before, when we used to have specific handsets like BlackBerry, Palm and Iphone. Also Android is leading consumers to a Smartphone evolution, which for old users can be a dramatic change.

In addition Google is attempting to bid on the 700MHz auction that will be vacated by analog TV in 2009. The rumours are about Google getting cheap calls for mobiles or even free internet access.

So how is Android affecting the other telecom providers? Well major mobile voice and data carriers in the U.S. have pledged to open their networks to outside handsets and applications. Carriers including AT&T and Verizon are already opening their network for outside handsets, however it is uncertain if this will cost more for consumers- And I'm not even talking about the Voip communication. One application that will come with Android is Gtalk which allows the user to make calls using internet protocol (IP) in case of mobile phone the WiFi would be used to do such thing, which could cause free phone calls.

These changes are pretty good on one hand as we will have more options as consumers, however we could face lack of support coming from telecoms as it would be more expensive to train personnel in different applications and OS.

Nobody knows if Android is coming to be a good thing for mobile companies and consumers, or if it's just Google's Achilles' heel like Steve Job quoted. What we know so far is that it is creating a good expectation.

Buying Bluetooth Helmets Online

Many motorcycle owners feel that they would still like to be in touch with friends and family while using their bikes. The advent of bluetooth technology has meant that this is now possible.

The idea behind bluetooth is that a headset can be fixed into your motorcycle helmet, allowing you to make and receive telephone calls. Since the systems is hands free, it is also legal in many countries. You need to check what the situation is in your own locality before making a purchase.

Bluetooth Helmets Explained

An increasing number of motorcycle helmets are making use of bluetooth technology to help owners make more of the riding experience. We offer an overview of what bluetooth helmets are all about.

To begin with, let's look at what bluetooth actually means. In basic terms, it's a form of wireless technology that allows various items of hardware to communicate. Those hardware items might range from computers to mobile phones. Unlike some other technologies, the range offered by bluetooth is actually relatively low - typically less than 30 feet.

When it comes to motorcycle helmets, the technology is used to enable owners to be able to make and take mobile phone calls while they are on their bikes. Such devices can be built into the helmet, ensuring that hands free operating is possible. This is vital since, in many countries, it is illegal to use a mobile phone whilst driving, unless it is hands free.

They are generally provided in such a way that you have some headphones that fit inside your speaker. You then have a microphone that protrudes from the front, allowing you to speak while you are driving. In essence, they are similar in design to many headsets that are currently on the market for internet based telephony.

The quality of helmets will vary considerably and the key is to find a unit that offers a good combination of comfort and quality. There's no point using one if it fits so poorly that you don't like using it. Similarly, there is nothing more frustrating than attempting to communicate when the sound quality is poor.

You can compare prices and reviews by using a number of websites that are currently available. Bluetooth helmets are here to stay and the quality of the devices is sure to improve in future years.

Bluetooth for Motorcycle Helmets

Bluetooth technology is fast becoming an integral part of many of our likes. Motorcycle owners are now able to take advantage of the technology to ensure that they are always available. If you're not familiar with bluetooth and how it works then don't worry - the concept is actually relatively simple.

The idea first came about in 1994 and was basically aimed at cutting down the number of wires and cables that are used in the average office or home. The technology allows various different pieces of hardware to communicate without wires. This is what is known as wireless communication.

Typically, the devices being used for this purpose might range from desktop computers and laptops to mobile phones. It is the use of mobile phones that is of particular interest to a growing number of bike and trike owners. Bluetooth helmets and headsets are now available that will allow communication, even when motorcycles are in use.

These systems are typically either built into a motorcycle helmet, or can be independent and be inserted into a helmet. They allow riders to communicate with others, potentially include mobile phones and landlines throughout the world.

Since they are hands free systems, they are often legal in many places where it is not possible to pick up the phone while driving. Does this all sound rather expensive? Fortunately, prices have been falling considerably in recent months. As the technology is developed, it's becoming more flexible and less costly to produce.

The quality of the equipment can be variable at the present time but standards seem set to improve as the devices grow in popularity. We can expect to see the growth in bluetooth helmets, allowing motorcycle riders to stay in touch at all times.

5 Tips to Consider Before Buying a Laptop Computer

There are many considerations to take into account before plopping down a large sum of money for a laptop computer. Consider first what you will be using your portable computer for, and then select the laptop that takes care of those needs. For example, if you just need a laptop to check your e-mail, light internet surfing, and word processing, you can probably get by with spending around $500 for a laptop. Here are some general guide lines to keep in mind, and make your decision a little easier.

Look for a laptop with alternate technology especially if you're on a budget. For example, a notebook utilizing an AMD processor is generally cheaper than one using an Intel processor. Choose a laptop that has at least 512 MB of memory. If that isn't possible, make sure that the laptop is upgradeable to 512 MB or more of RAM memory. It makes sense that the faster the processor clock speed is the faster your computer will run your programs. Choose a laptop with at least a 1.6 Ghz processor. This speed should put you in the Pentium 4 or higher class of CPUs. Select a laptop from one of the top manufactures such as Dell, Gateway, or Toshiba. This will insure you can get parts and service if you ever need them. Lastly, make sure your laptop has wireless capabilities. Many businesses and institutions across the US now offer free wireless web access. Most laptops manufactured in the last 3 years have this type of technology. If you are a road warrior this is a must have feature.

Free MacBook Pro? - Is it Possible to Get One Free?

If you are reading this article, then you have probably heard that its possible to get a Macbook Pro for free if you know the right place to look on the internet. Well, this is indeed true and not just some fanciful myth, and I am going to explain how and where you can do this, but first I want to explain to you just how it works, and how the companies that are doing this can get away with it without going completely bankrupt.

Well, first of all, you need to understand that you are not just going to get a free Macbook Pro without first doing something that benefits the companies that offer this deal. The way it works is basically this, you fill out a bunch of free signups, you refer a couple of friends to do exactly the same thing, and then you get your Macbook.

The companies can afford to give away free goods because they are being paid a certain amount of money for each person that gives the other companies (the ones that you do the free signups with) a name and email. The great thing for you, the consumer, is that although you will have to complete some pesky order forms (usually about 3-4) is that you will not be obligated to buy anything in future from any of these companies. You are not signing a contract to buy something.

Of course you always want to read the fine print with these offers, but on the most part, what I have described above is the way it works, and is the reason that these companies can afford to give away expensive goods for "free".

Its really a win win situation for all involved in the process, as unlikely as it may seem when you first hear about it. But it is, if you think about it, the customer gets something really cool for free, the company giving away the free thing makes money from the people signing up, and the companies whose offers you complete get a chance to offer you their services.
