Fourth Generation 1975-1985
Fourth Generation computers evolved from integrated circuit chip to the microprocessor. Thus putting into play the first functional desktop computers. This generation was the first introduction into mass production of early model desktops. The main goal of this generation computers was to reduce the size significantly due to companies wanting to sell them to the general consumers instead of just government officials. IBM introduced the first at home personal computer in 1981, having no competition until in 1984 Macintosh was created that allowed easier use of the system by using a cursor instead of just type text. Computers also developed a Local Area Network (LAN) that enabled people in local areas to share and converse information.
Some Early Desktop DIY Models:
The amount of CPU's increased from 2 million in 1981 to 5.5 million in 1982 then doubled with in 10 years.

Fifth Generation 1985-Present Day
Fifth Generation computers otherwise known as "artificial intelligence" that scientist wanted to outsmart humans and outlast inventor. In 1992 government officials wanted a way of having an "information superhighway" so the internet was invented so people could share information and find out things very quickly. Ideas from Al Gore were developed like the e-mail system of sending information to other computers with out using a LAN. This inspired many ways to use a computer thus leading to five types of CPU's.
