Generation of Computer

• 1st Generation (Vacuum Tube - 1946)
• 2nd Generation (Transistor - 1959)
• 3rd Generation (IC - 1965)
• 4th Generation (VLSI - 1971)
• 5th Generation (Artificial Intelligence)

First Generation

First generation computers used vacuum tubes. Example: ENIAC, EDVAC, UNIVAC

Second Generation

Second generation computers used transistors which made computers smaller and faster.

Third Generation

Third generation computers used Integrated Circuits (IC).

Fourth Generation

Fourth generation computers used microprocessors and VLSI technology.

Fifth Generation

Fifth generation computers use Artificial Intelligence and advanced technologies.
