In the most of the computer’s life span we encounter when we need to procure computer components or computer hardware as soon as possible to install in your computer, practically you run to the nearest computer stores in your locality and check whether if you can buy the computer hardware that you are looking. Sometimes, the computer hardware that you want is not available or if there is it is not compatible to your unit. In addition, people nowadays are looking for cheaper computer hardware that is not sold in second-hand computers stores. If this will occur, what would you do? You can freely ask your relatives or friends if they knew any best computer hardware store or possibly they themselves have the computer hardware that you are looking for which is not been use and still working.

When you are looking for any computer hardware store make it sure that the computer store you are choosing has good reputation and the most important is it has a good customer service.  At most time you want to know the details of the computer hardware that you are buying so the sales personnel of the store must be able to entertain your questions, if not then it doesn’t have a good customer service and it is time to look for another computer stores that offers good customer service. The best computer store must have good warranty ticket for you, and also, the computer stores must always be able to give you some tips and is willing to advice you regarding the proper installation, advantage, or disadvantage of every computer hardware it markets.

The best computer hardware store would have an easy accessibility that you may contact them very quick in case of any problems in their product that you bought from that store. It would be great if the computer store established computer hardware support center where you can contact professional people who are able to help you and even offers home service (you may not want to always carry your computer to the computer store in case of any problem that you can’t resolve by yourself, would you?). There are computer hardware stores that offer computer services in – line with their products, this would be advantageous in the future in building a better relationship with that computer store.

Lastly, if ever you didn’t find any good computer stores nearby. The online computer hardware stores will be your aid in this matter. You may buy your computer hardware through these online computer stores that would be willing to deliver it to your door. These would be better than none where you can always review that online computer store. But the best would be if you can access the computer store in your area because you can check the computer hardware freshly from their ledges unlike the online computer store.

The two main parts of a computer are hardware and software. The third – input- is what the computer user provides by using the computer hardware and software.

The computer hardware is all-inclusive term used to describe the physical parts of the computer as distinguished from the data it contains. Computer hardware is composed of computer itself, monitor, keyboard, printer, mouse and speakers. Inside the computer are more computer hardware bits including the motherboard where one can find the main processing chips that make up the Central Processing Unit (CPU). It is the computer hardware’s task to process the commands it receives from the software and to perform tasks or calculations.

Every part of the computer hardware is assigned to perform a specific task or tasks. The four main functions of computer hardware are: input, processing, storage and output.

Input is getting information into a computer system. The keyboard is the most obvious computer hardware component. A mouse, modem, cd and floppy disks could also be essential computer hardware components to input.

Data processing takes place in the Central Processing Unit (CPU). To aid the CPU is another computer hardware part that processes the arithmetic. It is the co-processor and called the Numerical Processing Unit (NPU).

Storage or where information is stored in the computer. The two main components are RAM (Random Access Memory) and hard drive.

Output is where you retrieve data. There are a number of ways in doing so. One computer hardware part is the monitor. It shows information from the computer so it is an output device. The monitor and parts of the computer that run it are called video. Another computer hardware output device is printer.

Computer hardware can be preserved for prolong use. The greatest enemy to computer is heat. Heat not only wears out internal components and chips; it also lowers performance of the system. The top and rear of the monitor should be kept clean. Dusts should be cleared from the inside surfaces of your computer hardware system system at least twice a year. The more dust on your chips, the hotter they get. A mere .005 millimeters of dust or enough to barely see. That much can raise the internal temperature by 5%. It is enough to shorten the system by years! Hard drives are also designed to be mounted flat. Mounting the unit flat distributes the weight of disk of hard drive evenly. This reduces wear and promotes long life.

Allow your computer to breathe and keep it clean, inside out and it will be around for years!

Both are two different methods of managing disks and improving the capacity and performance of hard disk drives.

Hardware RAID

A RAID can be described to be a hardware RAID when it gets implemented on hardware. This can be done on a motherboard or on another RAID card. The Windows takes the entire RAID to be one single disk. RAID controller controls the individual components of the disk and cannot be accessed directly by the Windows. RAID levels are generally implemented on the hardware based solutions. There are currently 7 major RAID levels, RAID 0, RAID 1, RAID 2, RAID 3, RAID 4, RAID 5 and RAID 6. The RAID which is hardware based provides disk drive protection against loss of data in media failure and it also improves performance of write/read operations. This dramatically increases the data transfer rates of the storage media. The performance with the hardware RAID depends on the configuration of the RAID. Hardware RAID gives an advantage of replacing the hard drive without shutting down the computer.  The main disadvantage of hardware RAID is that it is more expensive and you may be confined to a single vendor. Hardware RAID has more fault tolerance compared to software RAID.

Software RAID

Software RAID is also known as operating system based RAID. The software RAID may be done by the software that may be the part of the operating system or may be a part of the firmware and driver that comes with the motherboard. It implements the various levels in the block device code or kernel disk. It is the cheapest solution as compared to an expensive hot-swap chassis and disk controller cards.  Software RAID can also work with SCSI disks as well as IDE disks, which are very cheap. With the advancement of technology software can give better performance over hardware RAID. Software RAID is normally used in entry level servers and it requires only a standard controller.

If you have a software or hardware failure on RAID and require RAID recovery, you can buy RAID recovery software to unerase the data and files.
