When pascal invited computer in 1642 he did not know that it was a drawn of revolution.It was a simple machine of calculations, almost as big as a room. Somehow it could not attract the attention of other scientists or people.Hence,no valuable progress cold me made.
Computer consists of three major parts:
(1) Input media
(2) Output media
(3) Central processing unit(CPU)
Input media is the part of a keyboard.Output media is like television monitor which shows the result of CPU.CPU is the main component which calculates or processes the desired information.Computer is just like human brain. When we remember something,a visual or a related thing emerges on the screen of mind.Likewise,we ask computer to 'remember' something which is lying in its memory.It does so and shows the result on the screen of output media.
In this age of information technology, computer is man's real friend in order to store,manage, process and transmit information.From home to our office,from bank to our business and from bus terminal to airport computer serves us like an obedient servant.Atom bombs and missile batteries are controlled and operated by computer.
Its excessive use has made people introvert. They used to go out,play games,meet friends and other in parties,in functions or in festivals.
The rise of computer has widened the gap between haves and have-nots.The deprived sections of society cannot benefit from computer.
In the final analysis,the future of computer is very bright.We will not have to wait for a long time,when everyone enjoys its use.Our young ones would find it a kind assistant during their education and training.These days are not far off!
