Computer Components

All general purpose computers require the following hardware components:

(i) Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions.

(ii) Memory : It enables a computer to store, at least temporarily, data and programs.

(iii) Input device : Usually a keyboard or mouse is used to read data and programs into the computer.

(iv) Output device: A display screen, printer, etc. that lets you see what the computer has accomplished.

(v) Mass storage device: It allows a computer to permanently store large amounts of data. Common mass storage devices include disk drive and tape drive.
