Chapter Profile
Features of Third Generation Computer
These computers were made of ICs.
The use of the ICs reduced the size and increased the speed of the computers.
They were more affordable and dependable.
Fourth Generation (1970s)
In 1980’s, Very Large Scale Integration
(VLSI) came into existence in which
thousands of transistors were placed on
a single chip called microprocessor.
IBM released their first line of desktop
PC, which was used by the Intel 8088 chip Microprocessor
as their CPU. In 1983, IBM introduced the IBM PC
PC-XT, which had more memory and more hard drive space. In 1985, Microsoft released
the first version of Microsoft Windows.
Features of Fourth Generation Computer
VLSI called microprocessors invented.
Humans learned and grew
Small in size and could be placed on an office smarter, just like computers
table. have become faster and
smaller over time.
Hard disk to store data.
Introduction of GUI operating system.

Intel introduced the Intel 4004, the first microprocessor in 1971.
Fifth Generation (Present)
After 1986, VLSI technology was used to develop more powerful
microprocessors to improve the speed, size, cost and performance
of computers. In 1997, Intel introduced the MMX microprocessors,
which were designed to improve game and multimedia
performance. Scientists are still trying to develop computers with
Artificial Intelligence (AI).
