I have seen a Computer at my school and my parents work on a laptop at

about different types of Computers.
There are four types of Computers. Let me tell you about them.
Types of Computers
All types of computers have a CPU, keyboard, and a screen to display output. But
they differ in their size, cost and speed. Let us learn more about them.
On the basis of size and shape, Computers are mainly classified Microcomputer,
Minicomputer, Mainframe and Supercomputer.
