: A computer is a collection of device that helps people perform mathematical calculations. It is regarded as a special kind of electronic machine that can perform mathematical calculations and process large amount of data as a great speed. In a few minutes , a computer can perform calculation that a trained mathematician would need years to do. Though a computer can perform many complex jobs at a tremendous speed, it had no capacity to do anything by itself . It works on the basis of commands given by the operator.
A substitute for human brain: We live in a age of science. Science plays the most vital role in modern civilization. Now it has raised human civilization up to the highest peak.

It is computer which has come forward to work as a substitute for human brain.
Invention of computer: A British professor of mathematics named Charles Babes deserved the credit for the invention of computer. He wrote about a formula which would human brain. According to his formula, he made a machine. As electronic parts did not come into use at that time, he used metallic parts. As a result, the machine did not function properly. Following the formula of Charles Babes, an American scientist named Howard Akin invented an improved computer. It could do difficult sums. But the most modern computer made with electronic parts does wonderful things. The history of the invention of computer is a chronicle of continuous assessment.
Kinds of computer: Computers are of three kinds – the Analogue, the Digital and the Hybrid. An Analogue Computer can solve the difficult problems of mathematics within a very short time . A digital Computer can do varieties of things . It not only keeps accounts but also finds out defects of other machines and it tells about its solution. Nowadays, a computer means a digital computer . And a hybrid computer works with the help of Digital and Analogue computer. It is also called a mixed computer.
The parts of computer : A computer has mainly three parts-
1. Central Processing Unit
2. Input devices like keyboard, mouse, joysticks, floppy disks, etc
3. Output device include printer, monitor, etc.
The Central Processing Unit is the brain of computer . The input part receives signals and the output part gives the result.
