Types of computers

A computer is a device that takes in data, processes it according to a program, and then outputs the processed data in some form. There is an increasing variety of computers of different sizes and designed for different purposes. One of the most important considerations when buying a computer is deciding how it is going to be used. 

The modern computers are of three types called analog, digital and hybrid. An analog computer computes by using physical analogs of numerical measurements. A digital computer computes by using the numbers (digits) and yeses and noes expressed usually in 1’s and 0’s. A hybrid computer is a machine which combines some of the properties of digital and analog.

Computers can be divided into three broad categories: mainframe computers, minicomputers, and microcomputers. Mainframes are large, powerful, expensive computers that are operated by a team of professionals and are designed to be used by many people at the same time. The most powerful mainframes are sometimes called supercomputers.

Minicomputers are really cut-down mainframes and are no longer very common.

The most common type of computer is the microcomputer. Microcomputers are sometimes called personal computers. There is an increasing variety of portable microcomputers that can be grouped according to their size. However, as computers get smaller, it becomes more difficult to use them with a keyboard.
