8. Minicomputers are really cut-down mainframes and are no longer very common.The most common type of computer is the minicomputer. It was used to run basic, teleprint, and store 4k of memory for users who couldn't afford or didn't need a supercomputer. A mini computer has different uses among them being scientific calculations, business transaction processing and data base management. They are smaller in size than a normal laptop and are usually used when on the go or from anywhere, which gives them a big advantage. What is Computer? Categories of Computer 1. Mainframes 2.

9. 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 type of personal computers. However, microcomputers produced by Apple Computers in corporated are not normally referred to as PCs. There is a wide variety of microcumputers but two common types are dekstop computers and portables What is Computer? Categories of Computer 1. Mainframes 2. Minicomputers 3. Microcomputers

10. Dekstop are small enough to sit on an office desk and are relatively cheap. They becoming cheaper and more powerful and are often used for running multimedia programs, i. e. Programs that contains 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.

However, as computers gets smaller it becomes increasingly difficult to use them with keyboard. One of the reasons that notebook portables are popular is because their screens and keyboard are just big enough to use comfortablely for word processing. What is Computer? Categories of Computer 1.
