The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently. -
Transistors are smaller, more reliable, and generate less heat than vacuum tubes. This shift made computers smaller, faster, and more affordable. -
The computers of third generation used Integrated Circuits (ICs) in place of transistors. -
These computers used the VLSI technology or the Very Large Scale Integrated (VLSI) circuits technology. Therefore they were also known as the microprocessors. -
The fifth generation of computers was characterized by the development of artificial intelligence (AI) technology, which aimed to create computers that could perform tasks that would normally require human intelligence, such as reasoning, learning, and problem solving
