Features of Third Generation Computers:
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 its first line of desktop
Microprocessor
PC, which used the Intel 8088 chip as IBM PC
the CPU. In 1983, IBM introduced the PC-XT, that had more memory and hard
drive space. In 1985, Microsoft released the first version of Microsoft Windows.
Features of Fourth Generation Computers:
VLSI called microprocessors were invented.
They were in size and could be placed on an office table.
They had a hard disk to store data.
Led to the 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, that were designed to improve game and
multimedia performance. Scientists are still trying to develop computers with
Artificial Intelligence (AI).
Features of Fifth Generation Computers:
Will use artificial intelligence.
Improved size, cost, speed and performance.
New versions of GUI operating systems are being developed.
