Computer is an ultra modern
electronics device. It is a wonderful discovery of science. Modern world cannot
think without Computers. Computer has no capacity to work itself. It works on
the basis of command by the operator. Computers work with the combination of hardware
and software. Hardware means the component of the computer and software means
the program of the computer. After assembling hardware for a computer it needs
to set up some software for work. It works
in three stages, first one input stage, second one processing stage and third
one output stage. Now we are using computers in most of our work in our daily
life.
