Fourth-generation of computers
The computers we use today were invented around 1975.
These are much smaller in size and cheaper than their
previous forms. The fourth-generation computers use large
scale integrated circuits (LSIC), built on a single chip called
a microprocessor. The heavy processing unit of the
previous generations was replaced by the microprocessor.
Very large scale integrated (VLSI) circuits have replaced
the LSIC. These are generally called personal computers or
PC. These computers can be connected to form a network
using LSIC and VLSI technology, and they are connected

Answer:
The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.
Fourth generation computers became more powerful, compact, reliable, and affordable. As a result, it gave rise to Personal Computer (PC) revolution. In this generation, time sharing, real time networks, distributed operating system were used. All the high-level languages like C, C++, DBASE etc., were used in this generation.
