The document defines and describes different types of computers including microcomputers, minicomputers, supercomputers, personal computers, laptops, and tablets. Microcomputers are small and inexpensive computers that use a microprocessor as the central processing unit. Minicomputers are smaller than mainframe and mid-size computers. Supercomputers have a high level of performance compared to general-purpose computers. Personal computers are intended for individual use based on their size, capabilities and price. Laptops are portable personal computers with a clamshell form factor and keyboard and screen. Tablets are mobile touchscreen devices with mobile operating systems.

1. A computer is an Electronic device that is use to
take user input calculate data and give
meaningful output

3. A microcomputer is a small, relatively
inexpensive computer with a microprocessor
as its central processing unit (CPU).

4. A minicomputer, or colloquially mini, is a class
of smaller computers that was developed in the
mid-1960s and sold for much less than
mainframe and mid-size computers

5.  A supercomputer is a computer with a high
level of performance as compared to a
general-purpose computer. The performance
of a supercomputer is commonly measured in
floating-point operations per second

6. A personal computer is a multi-purpose
computer whose size, capabilities, and price
make it feasible for individual use.

7. A laptop, is a small, portable personal computer with a
"clamshell" form factor, typically having a thin LCD or
LED computer screen mounted on the inside of the
upper lid of the clamshell and an alphanumeric
keyboard on the inside of the lower lid

8. A tablet computer, commonly shortened to tablet,
is a mobile device, typically with a mobile
operating system and touchscreen display
processing circuitry, and a rechargeable battery in
a single, thin and flat package.
