modern science. It is an ultra modern electronic device of modern technology. It
does the function of storing and analyzing information. But it cannot do
anything by itself. It works on the basis of commands given by an operator. Charles
Babez, a British professor of mathematics, gave an idea that helped human
brain. Then Howard Akin, an American scientist, invented modern computer. A
computer has main four parts such as the input device, the output unit, the
memory unit, and the control unit. A computer mainly does three functions. It
receives data, processes it, and finally emits it. Computer is used for various
purposes. It does great service to mankind. It is now being used in various
fields like education, medical science, agriculture, trade and commerce,
printing, industrial sector, etc. It has lessened our work load, saved time and
distance, and made our life easy, comfortable, and enjoyable. But computer has
its own demerits too. It causes many diseases like cancer, brain tumor, high
blood pressure, etc. It weakens the eyesight of the operator. It is also being
used for destructive purposes in war field. However, we cannot go a single day
without computer. Now our duty is to make the proper use of computer only for
the welfare of mankind.
