ENIAC
The ENIAC was the first general-purpose modern electronic computer. It
was built in 1944 by JP Eckert and John Mauchly. It was, however very big
in size, consumed a lot of electricity and gave out a lot of heat.

Computer Generations
Each generation of computer is characterised by a major technological
development that fundamentally changed the way computers operate,
resulting in increasingly smaller, cheaper, more powerful and more efficient
and reliable devices. Electronic computers are mainly classified into five
generations. These are:
Computer Generations
1st Generation 3rd Generation 5th Generation
2nd Generation 4th Generation
Types of Computers
Since the advent of the first computer, different types and sizes of
computers are offering different services. Computers can be as big as
occupying a large building and as small as a laptop or a microcontroller in
mobile and embedded systems.
