Passage: Monitors, keyboards and other devices for input and output may be integrated or separate. Computer memory in the form of RAM, and at least one other less volatile, memory storage device are usually combined with the CPU on a system bus in one unit. Other devices that make up a complete microcomputer system include batteries, a power supply unit, a keyboard and various input/output devices used to convey information to and from a human operator (printers, monitors, human interface devices).  Microcomputers are designed to serve only one user at a time, although they can often be modified with software or hardware to concurrently serve more than one user.  Microcomputers fit well on or under desks or tables, so that they are within easy access of users.  Bigger computers like minicomputers, mainframes, and supercomputers take up large cabinets or even dedicated rooms.
