Explain the five generations of computer

1First Generation

The period of first generation: 1946-1959. Vacuum tube based.

2Second Generation

The period of second generation: 1959-1965. Transistor based.

3Third Generation

The period of third generation: 1965-1971. Integrated Circuit based.

4Fourth Generation

The period of fourth generation: 1971-1980. VLSI microprocessor based.

5Fifth Generation

The period of fifth generation: 1980-onwards. ULSI microprocessor based.

First Generation of Computer (1940-1956)

The First Generations of computer used vacuum tubes in their hardware circuit and magnetic drum for their memory. They were gigantic in size and were kept in an enormous room.

Second Generation of Computers(1956-1963)

The Second generation of computers utilized “Transistor” instead of huge vacuum tubes. The transistor was designed and invented in 1947 by three physicians Bardeen, Brattain, and Shockley.

Third Generation of Computers(1964-1971)

The Third Generation of computer used Integrated Circuit (I.C) rather than vacuum tubes and transistors. Jack Kilby in 1958 created the Integrated Circuit. Number of other component and segments were used in a single silicon chip like Transistor, Resistor, and Capacitor and were called as “Semiconductors” which drastically improved and enhanced the speed, reliability, efficiency, and dependability.

Fourth Generations of Computers :: ( 1971-To Present Day)

The Fourth Generations of Computer used “Microprocessor” Instead of vacuum tubes and transistors. The PC that uses Microprocessor [CPU] is called as “Micro-Computers”. Microprocessor or Microchip are developed using Large scale Integration.

Fifth Generations of Computers (Present and Beyond)

The Fifth generation of computers are in a development face which uses AI (Artificial Intelligence).This types of computer will be very smart they will take their own decision.
