It is the best invention of modern science as it has opened a lot of new scopes of knowledge and work. Since the primitive time man is inquisitive. He is inventing new things just to solve the problems of life, to save time and to enrich human knowledge. Computer has so far given the scope of both educations just to keep pace with the advanced world. Otherwise it will lag behind.

The root of computer is ‘compute’ that means to do math or to calculate something. It is a device for storing and analyzing information fed into it. It makes calculations and controls the machinery automatically. It is a set of four things generally, a monitor which has a screen, a PC, a mouse and a key board.

The main parts of a personal computer are:

b. The output unit
c. CPU or Central Processing Unit.

The CPU is further formed of three units. There are:
