The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and recollection to input/output controls—on a single chip.
In 1981 IBM introduced its first computer for the home utilizer, and in 1984 Apple introduced the Macintosh. Microprocessors withal moved out of the realm of desktop computers and into many areas of life as more and more everyday products commenced to utilize microprocessors.
As these minute computers became more puissant, they could be linked together to compose networks, which eventually led to the development of the Internet. Fourth generation computers withal optically discerned the development of GUIs, the mouse and handheld contrivances.
