What is third generation of computer

In the third generation of computers, integrated circuits (ICs) were used instead of transistors, introduced in 1958 by J. s. Kilby (J.S. Kilby). LSI technology was used in this. In which thousands of transistors were used on a single silicon semiconductor microchip. Which is known as Large-Scale Integration (LSI). It worked much faster than the first generation and second generation computers, they were also smaller in size and cost less.
