Computer is the most wonderful contribution of modern science . It is an ultra-modern electronic device of modern technology . But it has no ability to do anything by itself . It works on the basis of commands given by the operator . It can solve many complicated problems within a short time .
Invention And Development :
Computer was invented by the hard work of many scientists . Charles bavez is called the father of modern Computer . He invented the structure of Computer at first in 1833 . His invented computer had five parts . These were Store , Mill, Control , Input and Output . By following the structure of computer of Bavez , Harvard University and I.B.M . company combindly invented the modern electric computer in 1944 .

inspite of having uncounted merits of computer’s , it has also some demerits . It weakens the eye – sight of the computer .
The computer is a blessing of modern science . We cannot go a single moment without it . It lessens our works and makes our lives easy and simple . But it has not been fully introduced in all country . So we should use it all over country .
