A Computer
A Computer is a machine that can
process, store and retrieve information. It can perform three basic functions:
(i) add, subtract, multiply, divide; (ii) compare values; and (iii) store,
search and retrieve.
The computer technology has
changed fast from personal to mini, micro and super computer form. We can also
quick and correct calculations, maintain heavy data and information and to a
variety of other jobs by means of computers.
It is an electronic means to
receive, store and calculate data in the fastest way. A simple computer was
first made by Charles Babbage in the 19th century. The computer age actually
started in 1946 in the U.S.A.
It possesses no intelligence of
its own. Only the user can determine what tasks a computer will perform. A
computer can only perform tasks that human beings can.
The difference is that computers
perform these tasks with unthinkable speed and accuracy. In a computer, a disc
called floppy is inserted which holds a programme.
A Programme consists of several
thousand typed pages. A computer can scan through this disc in a matter of
seconds and can perform accordingly.
