Generation in computer terminology is a change in technology a
computer is/was being used. Initially, the generation term was used to
distinguish between varying hardware technologies. But nowadays,
generation includes both hardware and software, which together make up
an entire
computer system.
There are totally five computer generations known till date. Each

characteristics. We've used approximate dates against each generations
which are normally accepted.Following are the main five generations of computers
