Types of computer

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.

Computers can be divided into three broad categories: mainframe computers (mainframes), minicomputers (minis), and microcomputers (micros). 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. The abbreviation PC was originally used for microcomputers produced by IBM Corporation, but it is now sometimes used for other types of personal computer. However, microcomputers produced by Apple Computers Incorporated are not normally referred to as PCs. There is a wide variety of microcomputers but two common types are desktop computers and portables. Desktops are small enough to sit on an office desk and are relatively cheap. They are becoming cheaper and more powerful and are often used for running multimedia programs, i.e. programs that contain some combination of text, sound, high quality graphics, animation, and video. Multimedia computers need to have a sound facility and usually have a CD-ROM drive.

There is an increasing variety of portable micros that can be grouped according to their size. They can usually be powered from batteries and are useful in many different situations. However, as computers get smaller, it becomes increasingly difficult to use them with a keyboard. One of the reasons that notebook portables are popular is because their screens and keyboards are just big enough to use comfortably for word processing. They can also be powerful enough to be used for multimedia. The relative size of some of the most common types of computers is indicated below, although there are other types that are not mentioned here and new types are currently being developed.
