Circuits (ICs) made computers smaller, more efficient,
and capable of storing more data.
Features of Third Generation Computer
These computers were built using ICs.
The use of the ICs reduced the size and increased the processing
speed of computers.
They were more affordable and dependable.
Fourth Generation (1970s)
Fourth-generation computers are
a type of computer that came out
in the 1970s and 1980s. These

thousands of transistors are placed
on single tiny chips called microprocessors.
IBM released their first line of desktop PCs in 1981, known as the IBM PC, which used
the Intel 8088 chip as its CPU. In 1983, IBM released the PC-XT, which had more
memory and a larger hard drive. Then, in 1985, Microsoft introduced the first version
of Microsoft Windows known as Windows 1.0.
Features of Fourth Generation Computer
