Another name for microcomputer. The term is also used, more specifically, to mean the IBM Personal Computer and computers compatible with it.

The first IBM PC was introduced in the USA in 1981; it had 64 kilobytes of random access memory (RAM) and one floppy-disk drive. It was followed in 1983 by the XT (with a hard-disk drive) and in 1984 by the AT (based on a more powerful microprocessor). Many manufacturers have copied the basic design, which is now regarded as a standard for business microcomputers.
