These are also known as Personal Computers. These type of digital computer uses a microprocessor (a CPU on a single chip) and include both desktops and laptops. These computers can work on small volume of data, are very versatile and can handle variety of applications. These computers are being used as work stations, CAD, multimedia and advertising applications. Small portable computers such as PDAs (Personal Digital Assistants) and tablets with wireless computing technology are increasingly becoming popular.

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.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 keyboardand screen for input and output) are also personal computers (in the generic sense).

The first microcomputer was the Japanese Sord Computer Corporation‘s SMP80/08 (1972), which was followed by the SMP80/x (1974). The French developers of the Micral N (1973) filed their patents with the term “Micro-ordinateur”, a literal equivalent of “Microcomputer”, to designate a solid state machine designed with a microprocessor. In the USA, the earliest models such as the Altair 8800 were often sold as kits to be assembled by the user, and came with as little as 256 bytes of RAM, and no input/output devices other than indicator lights and switches, useful as a proof of concept to demonstrate what such a simple device could do.
