Third Generation (1960s)
The third generation began with the invention of Integrated Circuits (ICs) which led to smaller-
sized computers with better functioning and more storage.
Features of Third Generation Computers
These computers were built using ICs.
The use of the ICs reduced the size and increased the
processing speed of computers.
These were more affordable and dependable.
Integrated Circuits
Fourth Generation (1970s)
In 1980s, Very Large Scale Integration (VLSI) came into existence in which thousands of
transistors were placed on a single chip called a microprocessor.
Microprocessor IBM PC
IBM released their first line of desktop PCs in 1981, which used the Intel 8088 chip as their CPU.
In 1983, IBM introduced the PC-XT, which had more memory and more hard drive space. In
1985, Microsoft released the first version of Microsoft Windows.

Fifth Generation (Present)
Fifth-generation computers are the smartest computers we have
today. They use advanced technologies like artificial intelligence. These
computers can think, learn, and understand what we say. They can
do many things at the same time and are used in smart devices like
voice assistants, smartwatches, and self-driving cars. Even though
we already use some fifth-generation computers, scientists are still
working to make them even better.
