How many Generations of Computer are there in computer world is jotted below that will help you test your basic computer knowledge by medium of this article.
1st Generation of Computer – Vacuum tube based
Computer – First Generation:- The first generation period was from 1946–1959. First generation computers used vacuum tubes as basic components for memory and circuitry for CPUs (central processing units). These tubes, like electric bulbs, produced too much heat, and the installation often fuses.
2nd Generation of Computer – Transistor based
Second Generation:- The Second Generation Computer period was from year 1959-1965. A transistor computer, now often called a second generation computer, is a computer that uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes to generate large amounts of heat, they were heavy and unreliable.
3rd Generation of Computer – Integrated Circuit based
Third Generation:- The Third Generation Computer period was from year 1965-1971.Third generation computers used integrated circuits (IC) instead of transistors. A single IC consists of multiple transistors, resistors, and capacitors with associated circuitry. This development made computers small in size, reliable and efficient.

4th Generation of Computer – VLSI microprocessor Technology based
Fourth Generation:- The Fourth Generation Computer period was from year 1971-1980.Fourth generation computers used very large scale integrated (VLSI) circuits. The VLSI circuit consists of about 4999 transistors and other circuit elements with circuits connected on a single chip, making it possible to have a fourth generation microcomputer.
5th Generation of Computer – ULSI microprocessor based
Fifth Generation:- The Fifth Generation Computer period was from year 1980-till date.The VLSI technology became the ULSI (Ultra Large Scale Integration) technique, resulting in the production of microprocessor chips with ten million electronic components. This computer generation is based on parallel processing hardware and AI (artificial intelligence) software technologies.
