A small but powerful Computer primarily used in an office or home without need to be connected to a larger
computer. PCs evolved after the development of the Microprocessor made possible the hobby-computer movement of the late 1970s, when some
computers were built from components or kits. In the early 1980s the first low-cost,
fully assembled units were mass-marketed. The typical configuration consists of
a video display, keyboard, logic unit, storage device and, frequently, Modem. Some current PCs have more computing power than the large mainframe
computers of the 1950s and early 60s.
