1965 - 1970	LSIC,VLSIC	Nano/Pico	very low cost

1. The microprocessor was used in the fourth generation computers, as thousands of integrated circuits were built onto a single silicon chip.

2. The Intel 4004 chip, developed in 1971, located all the components of the computer – from the central processing unit and memory to input/output controls – on a single chip.

3. In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh.

4. Network technology was introduced at this time. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.
