Basic Part of Computer Hardware

If you are using a desktop computer, you may already know that there isn't any single part known as a "computer". A computer is a system of several parts working together. The physical parts which you could see and touch are jointly known as hardware. There are some computer hardware parts which collectively form a computer.

Computer Hardware Parts:

System Unit

The system unit is the heart of a computer system. Generally, it's a rectangular box placed on or beneath your desk. There are several electronic components which process information inside this box. The most vital of these components is the central processing unit (CPU), or microprocessor, which acts as the brain of your computer. Another component is the RAM or the random access memory which temporarily stores data that the CPU uses while the computer is on. When the computer is turned off, the information stored in RAM gets erased.

Hard Disk Drive

Your computer's hard disk drive stores data on a hard disk, a firm plate or stack of plates with a magnetic surface. The hard disks normally serve as your computer's primary means of storage, holding almost all of your programs and files as it can hold enormous amounts of information. The hard disk is usually located inside the system unit.

DVD and CD Drives

Almost all computers today come equipped with a DVD or CD drive, generally located on the front of the system unit. CD drives use lasers to read or retrieve data from a CD and several CD drives could also write or record data onto CDs. DVD drives could do everything that CD drives can plus they can also read DVDs. If you have a DVD drive, you could watch movies on your computer. Several DVD drives could record data onto blank DVDs.

Floppy Disk Drive

Floppy disk drives store information on floppy disks, also known as floppies or diskettes. Floppy disks compared to CDs and DVDs can store only a small amount of data. They also recover information more slowly and are more prone to damage. For these reasons, floppy disk drives are less admired than they used to be, though some computers still include them.
