Firstly, the functions of the parts of the computer could be likened how the human body function.

It’s the brain of the computer system.

Secondly, the processing device which is also called the processor is that part of the computer that works on the information supplied.

The processor and all other parts form are called the Central Processing Unit (CPU).

Thirdly, It’s housed by that box called casing, the casing could be vertical(Tower Top) or horizontal (Desktop).

Fourthly, the rate at which information is processed by the CPU varies and it depends on:

1. The processor speed (Pentium IV, Pentium III, Pentium II or Pentium.

2. Available RAM (Random access memory) size.

However, the motherboard is the layout on which the components of the computer are attached inside the system units.

ALL ABOUT THE COMPUTER STORAGE DEVICES

Still, Storage devices are used to hold data (information) in the computer and also to transfer data from one computer to another.

EXAMPLES OF STORAGE DEVICES

1. Hard Disk

2. Floppy Diskette

3. Zip Diskette

4. Tape

5. Flash

6. Compact Disk

Thus, the storage device is kept in housing called DRIVE.

There are two types of Drive

2. Non-removable Drives

Therefore, removable drives are just like the name sounds, those devices that can be removed from their housing.

Examples are the Floppy Disk, Compact Disk, etc.

1024 KB                                         1 MB
