A small computer, with a processor made of one or a few integrated circuitsthumb|Raspberry Pi, a popular microcomputer. A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory and minimal input/output (I/O) circuitry mounted on a single printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). thumb|The Commodore 64 was one of the most popular microcomputers of its era, and is the best-selling model of home computer of all time. The abbreviation micro was common during the 1970s and 1980s, but has now fallen out of common usage.
