Shopping for Hardware

Shopping and computers may not seem like a good match. Fashion, however, says otherwise. With the world becoming more and more reliant on technology, the internet and connectivity, it is almost impossible to ignore that fact that almost everyone in this world has to have a mobile phone, pocket PC or even a WiFi internet device.Everyone means everyone, that means even people who have never fiddled around with a computer are now faced with a form of social isolation if they do not have access to hand held electronic gadgets. Realizing this demand, the manufacturers of consumer electronics have not only pushed forward with innovations in the field of technology but also created new stylized look for their products.Enter the World of Fashionable Hand held Electronics The mobile phone is the most essential gadget of all, and you most probably have owned more than one. After all, phones help keep people in touch and coordinate with their friends and family. Events become easier to handle and almost any form of social interaction can be organized by sending just a few well placed text messages. When you find yourself shopping for a mobile phone you will be balancing both style and function as you choose among the hundreds of devices out there on the market today. This choice is very dependent on your personal requirements. Most touch phones have sleek black glass or a shiny metallic finish; they are usually very thin and light, but with ample width for the screen.Another important electronic that you should shop for is the pocket PC, while some mobile phones may have the same capabilities as a pocket PC, you might want to have dedicated device for all your office and professional needs. When shopping for a pocket PC, you should first make a list of all the tasks that you do when you are on the go; then find a suitable device that would enable you to accomplish those needs. The pocket PCs may look similar to each other but they have very different looks. Choosing one with the right style and form to match your personality will take a little effort.Making Your Gear More Personalized You should do more than just shop for electronics. You should also keep an eye out for good deals on carry cases, protective covers, accessories and straps. These not only add an additional visual flair to your gadgets, but they also serve very functional purposes. Straps and laces allow you to hang your phone or gadget on your wrist, around your neck or even on your bag.Just be sure to get one that is as sturdy as it looks good so that your gadgets will not get damaged. Decals and stickers are also good for decorating your gadgets. Many stores carry these and you do not have to restrict yourself to electronics stores to find good decals.Sports stores, hobby shops and toy shops often have good stickers that would also look good on your gadgets. Remember, when it comes to shopping for electronics, getting excellent functionality for your money is easy if you invest enough time and effort to study what would make you happy.

How to Sell Used Computers

Many people sell their used computers for a variety of reasons. Some sell their used computer instead of throwing them as a trash get some money from them, while others sell their used computers to buy new computers with the latest features and technology. Not only individuals sell their used computers, but also large numbers of organizations or firms sell their used computers. They do so because the computer systems may require maintenance and repairs, after some time due to the decrease in performance seen in the computers after some years. Instead of spending more money on the maintenance and repairs they sell and gain money, as there is a great demand for used computers. Such companies easily sell their used computers online through auctions or exchange for new computers with less effort in no time.
Used computers are bought by either students who do not have good savings or earnings or they are bought by educational institutions like the schools and universities. Some parents buy used computers for their children just for browsing the Internet and to play games. For this purpose, a used computer is more than sufficient than spending huge amounts on a new computer. These target segments however require used computers in a good working condition as well as for a lesser price. Most of the used computers are sold in the online market, as it attracts all sorts of buyers. There are many numbers of online classifieds or auctions or online dealers who sell used computers. Selling used computers are a better option than throwing them as trash or keeping them in a corner occupying space and collecting dust.
The first and important step is to improve the appearance of the used computer by wiping it clean free of dust and dirt. Any buyer would get impressed by the way the computer looks, looks make the first impression. The selling price of a clean used computer is always better than the one, which is full of dirt and dust.
All the software manual, operating system and other supporting discs that came with the computer should be in tact. This will add more value, when selling the used computer and also will make the buyer consider the person who is selling the used computer as a trusted seller.
The most important thing to do before selling a used computer is to erase all the personal details or information from the hard disk or drive. Instead of just putting them in the trash folder it is very important to purge all the personal data from the computer’s memory, even invisible backup files can cause danger. A tech savvy person’s help can be got if the seller does not know how to do it. If not done it may lead to accessing the bank accounts, or emails by any unknown person leading to identity theft. For that when there is a remedy. Unused scanners, printers can also be bundled with the sale of the used computer. A buyer may sometime value it. The benefits or features of the computer can be highlighted for better sales.

Hard Drives- Choosing the Right One

Summary:
When buying or building a home computer, it is important to make sure your hard drive is the proper size. Without the proper hard drive, you'll find using your computer won't be as much fun as you want it to be.
Keywords:
hard drive, RAID, choosing, choose, new, buy, help, hard disk, GB
Article Body:
Hard drives come in many different sizes and configurations. How much data a hard drive can hold is measured in gigabytes (GB). The latest hard drives can hold anywhere from 80 GB to 1000 GB (1 TB)! When buying a hard drive, size isn't the only factor to look at, however. By choosing the right hard drive for your needs, you'll enjoy your computer more. Hard drives are inexpensive and you should never skimp on one to save money.
For business or basic home use, an 80 GB hard drive should suffice. If you plan on downloading music, movies, or installing a lot of games on your computer, your hard drive should be at least 160 GB. For laptop users, the same space requirements apply, however, many laptops come with small hard drives. Many laptop users choose to keep the small hard drive and buy an external hard drive for excess files to keep costs down.
You can have a huge hard drive, but it will be worthless if it doesn't move data fast enough for your computer! To find data, hard drives have platters on spindles that spin, similar to a CD. How fast a hard drive spins is measured in RPM (revolutions per minute). The higher a hard drive's RPM is, the faster it will perform. Desktop hard drives almost always have 7200 RPM hard drives. Laptop hard drives can range from 4200 RPM to 5400 RPM for budget and midrange uses and 7200 RPM for high end use. Hard drives with RPMs of 10,000 or more are available, but those are mainly for gamers, computer enthusiasts, and servers.
If you are computer user looking for performance, you should know about RAID. RAID lets you put 2 or more hard drives of the same brand and model together and run them at once, which results in faster performance. You can also use RAID so the second hard drives automatically backs up data from the first hard drive, so you always have a backup of your data. There are numerous possible RAID configurations out there, too many to mention in this article.
A hard drive's cache is also another important performance indicator. A hard drive's cache will hold frequently accessed data for faster access by the computer. A good hard drive will have at least 8 MB of cache. As with RPM, the more cache a hard drive has, the better.
Hard drives generally have either an SATA or IDE connection. Both connections are for attaching the hard drive to the motherboard via a cable so that data can be sent and received to and from the computer and drive. SATA is the newest connection and is better than IDE in that it can be faster and uses a much smaller cable. IDE, however, is just as fast as IDE in real world performance testa and hard drives that use IDE are cheaper than SATA hard drives. However, IDE hard drives use large cables that can restrict airflow. Fortunately, you can buy a rounded IDE cable that is not as big for $5-$10 at almost any computer supply store or online computer part retailer, such as Newegg.com or Fry's Electronics.

A Safer Way to Recover Damaged Partitions

Repairing damaged partitions on is a risky business. Even if you use the best toolkit and are absolutely sure in what you are doing, you are still risking your files shall something go wrong. Changes made to the damaged partition are irreversible; it is just too easy to overwrite an important system structure that holds vital information about your disk, files and data. Bottom line: it's good to backup before performing data recovery. But is this really the best way to do it?
There is a different approach to do data recovery that is even safer. No need to backup and restore during the recovery. Instead of making a backup copy of corrupted data, you can simply take a binary snapshot of the partition being repaired, and attempt the recovery with different settings as many times as you need on this snapshot instead of the actual disk.
SoftAmbulance Partition Doctor by http://softambulance.com/ is one of a few data recovery tools that allow recovering a virtual image of a damaged hard drive instead of repairing the hard drive directly. The data recovery tool lets you create a binary image of the damaged hard drive, and works with the binary image instead of the real thing. The binary image is a big file stored on another hard disk, CD, DVD or other media. The technology is similar to making an .iso image of a CD or DVD disc, only SoftAmbulance Partition Doctor extends it to partitions or even entire disks.
The hard drive copy may be virtual, but any data you save from it is for real. SoftAmbulance Partition Doctor can recover your files, documents and other data from the binary image and put it on a healthy media. After that, you can attempt fixing the damaged system structures of the corrupted hard drive without taking any risk at all. Any modifications will be performed on the virtual image.
Don't rush the recovery. Don't take the risk of losing or corrupting your data. Create a virtual snapshot of the hard drive being repaired, and work on that snapshot instead of accessing the corrupted hard drive. This procedure keeps your original data safe, and ensures the highest level of safety during the recovery process.
SoftAmbulance Partition Doctor recovers files from damaged and corrupted disks and partitions and fixes damaged hard drives. The disk recovery product supports all 32-bit versions of Windows, and recovers FAT and NTFS formatted hard disks, memory cards, CD and DVD media, and USB flash drives. The evaluation version is available for free at http://softambulance.com/

Data Recovery - What To Do When Your Hard Drive Fails

How many times have you experienced that sickening feeling when your hard drive suddenly fails? How many times have you experienced that your hard disk just does not boot and all the data may be gone forever? A hard drive failure is one of the most common problems and worst nightmares faced by computer operators all over the world. Precious data is lost either at home or in big corporate environments. What can be done in these situations? Well, there are certain solutions that can be performed by you in order to revive your hard drive. We will talk about the solution later. First, let us discuss why a hard drive fails.
Whether the data on the hard drive can be recovered or not depends on the extent of the problem. A hard drive can be damaged due to firmware corruption, electronic failure, mechanical failure or a logical failure. Many times your hard drive may lose data due to the combination of the above mentioned factors. A hard drive may also develop bad sectors due to which the data on those sectors is lost or becomes unreadable.
Firmware refers to the information used by the computer to interact correctly with the hard drive. If the firmware fails or becomes corrupted, then important data on the hard drive is lost. In case of an electronic failure there maybe occur an electrical surge that can knock out the controller board on the hard drive and make it unusable. However data can be recovered by data recovery experts who use special data recovery software. Swapping the controller board with another one can prove to be dangerous as the information on the controller board is unique to the hard drive on which it is fitted. In comparison to electronic failure a mechanical failure can turn out to be worst as data recovery can almost become impossible. Mechanical failure includes head crash and also read/write head failure. Head crash can occur due to physical shock, power surges and movement of the computer. Next come the logical errors. Logical errors have nothing to do with the hardware part. Logical errors can occur due to corruption of the file system on the hard drive or improper entries in the file allocation table.
In case of hard drive failure it is vital to call the data recovery experts. In most cases, the information on the hard drive is important and you cannot bear to lose it. The experts enhance the possibilities of hard drive recovery in the case of failure of hard drive due to software malfunction, virus attacks and other reasons mentioned above. Data can be recovered on any type of operating system including all versions of Windows as well as Apple Macintosh, Novell, Linux, Unix and also on all types of file systems like FAT, FAT32, NTFS, NTFS5, HFS, HFS+, NWFS, EXT2 and EXT3. The experts may take the hard drive to their workshop in order to recover the lost data and then return it to you in a few days. Most of the data recovery experts have their own laboratories that are involved in testing the hard drives and repairing them.
Loss of data is the last thing that you as the customer would ever want. This is where the data recovery experts come into the picture. They cannot extract only data from hard drives, but recover data also from tape drives, cds, dvds and other important storage media. You as the consumer can take up some preventive measures like backing up all your important data at least once a week. Windows has its own feature rich backup program. There are other backup software programs available in the market that can avert a possible disaster.
Besides the concern of recovering your data, another problem is the time it may take for an expert to help. This can be a slow and tedious process. I recommend having a second complete computer source such as a laptop (for portability) that you can continue your work. This way you are never completely down and you can share important data between the two.

Computer Speakers

Few people think too long and hard about their computer speakers, instead preferring to just use the ones that came with their computers. These speakers are often built-in and poor quality, especially on laptop systems, and do not do justice to the very good sound quality that most computers are capable of producing.
The price range in computer speakers is even greater than that in other electronic products – you can pay anywhere from the price of a pair of headphones to as much as the computer itself cost you. It is natural, therefore, to be unsure of exactly what your money is getting you, which is where this article can hopefully be of some help.
Perhaps the most important thing you should look for when choosing your speakers is their maximum output power, which is measured in watts. This number tells you how good the speakers will sound at different volumes – while almost all speakers can sound good at low volumes, only ones with very high maximum output power will sound good at higher volumes. The higher the volume you plan to use, the more power you need.
Another important consideration is whether the speakers can produce either 5-speaker or 7-speaker surround sound, which makes a big difference over traditional 2-speaker systems. You should also check whether the speakers come with a sub woofer, which is a special loudspeaker for bass, allowing you to better hear the beat of your music. However, many people actually consider sub woofers undesirable, as they are so large and don’t always fit in well with a computer setup.
It is only really worth splashing out on speakers if you often use your computer for gaming or for playing music. If you do, then you might consider that there’s nothing to say so-called ‘computer’ speakers are only for computers – with a little imaginative wiring, you can also hook them up to televisions, games consoles, mp3 players, and all sorts of other things besides. This works in reverse, too, so if you already have a good pair of speakers, it should be relatively simple to connect them up to your computer and get some very good sound that way.

How to Add Memory to your computer

A lot of people think they are ready for a new computer when their current one begins showing signs of old age. If you have already performed other steps to speed your pc performance to no avail, you may want to consider adding memory (RAM).This is a very effective way to save money by prolonging the life of your pc by a few years.There are so many types of memory like physical memory virtual memory random access memory etc.

Ultra mobile pc,s

Ultra Mobile PCs are a strange breed; some would say neither fish nor fowl. They aren't fully fledged laptop computers; no optical drive, not the same array of ports and connectors, small screen. They aren't handhelds; they run a ‘proper' operating system and are intended for ‘real' computing.
So where do they fit in the scheme of things, and can they find a place for themselves? Well, the jury is out, but while it ponders (which means while people decide whether they will buy the things in sufficient numbers to keep them being produced and updated), there does seem to be a steady flow of them, and OQO has done its fair share of producing new devices. We make the OQO model e2 the third we've seen.
It is similar to its predecessors in that it has a slide-out keyboard and a small format: 142mm wide, 84mm tall and 26mm thick, and weighing 450g. It looks stunning thanks to its shiny black casing.

What is Computer First sign of old age

A computer's first sign of old age can be either subtle or obvious. However, if the computer decides to let you know it's beginning to show some wear, you can look for some common signs.Computer making is started from very old ages we can say Abacus is a form of computer it is mostly used by chinese for calculations

To build your own computer

When you have all component parts, you are ready to assemble the computer system. If you are a beginnner, assembling the entire system might be a little tricky. Some things you will want near you while doing this job is plenty of light, computer screws, all the manuals that came with the hardware you purchased, a screw driver and of course, a bottle of icy cold drink to keep yourself cool.

How to Assemble a system

In assembling a computer, the main points to consider are purpose, availability, compatibility, and cost. Before building a system, ask these questions: What is the computer needed for? Are the parts for this computer available? What is the compatibility of the parts? Is this computer within the budget? The answers to these would serve as a guide in assembling the right computer.

HP lcd

HP’s LE2201w 22-inch LCD monitor is pictured above.Nothing much to look at, but I like it that way: simple. There is also the 19-inch version: LE1901w. Both of these monitors are billed as “Eco-Friendly” by HP. But, before I get into the merits of how eco-friendly these monitors really are, let’s look at some basic specifications for the 22-incher:

Control

Control units are in charge of the computer. Control units fetch and decode machine instructions. Control units may also control some external devices.
A bus is a set (group) of parallel lines that information (data, addresses, instructions, and other information) travels on inside a computer. Information travels on buses as a series of electrical pulses, each pulse representing a one bit or a zero bit (there are trinary, or three-state, buses, but they are rare). An internal bus is a bus inside the processor, moving data, addresses, instructions, and other information between registers and other internal components or units. An external bus is a bus outside of the processor (but inside the computer), moving data, addresses, and other information between major components (including cards) inside the computer. Some common kinds of buses are the system bus, a data bus, an address bus, a cache bus, a memory bus, and an I/O bus.
