GENERATION OF COMPUTERS

FIRST GENERATION SECOND GENERATION THIRD GENERATION FOURTH GENERATION FIFTH GENERATION

FIRST GENERATION(1940-1956)FIRST GENERATION(1940-1956)

The first generation computers used vacuum The first generation computers used vacuum tubes.tubes.

It was invented by Lee De Forest.It was invented by Lee De Forest. They came into existence in 1940.They came into existence in 1940. They were very huge.They were very huge. It consumed a lot of electricityIt consumed a lot of electricity

VACUUM TUBESVACUUM TUBES

SECOND GENERATION(1956-SECOND GENERATION(1956-1963)1963)

Transistors were used in second Transistors were used in second generation computers.generation computers.

They were invented by William Shockley.They were invented by William Shockley. They came into existence in 1956.They came into existence in 1956. The transistor was far superior to vacuum The transistor was far superior to vacuum

tubes.tubes. This helped the computers to become This helped the computers to become

smaller, faster and cheaper.smaller, faster and cheaper.

THIRD GENERATION(1964-1971)THIRD GENERATION(1964-1971)

Integrated circuits were used in third Integrated circuits were used in third generation computers.generation computers.

They were invented by Jack Kilby They were invented by Jack Kilby and Robert Noyce.and Robert Noyce.

They came into existence in 1964.They came into existence in 1964. They were very small in size.They were very small in size. Production cost was very cheap.Production cost was very cheap.

INTEGRATED CIRCUITS

FOURTH GENERATION(1971-PRESENT)

The microprocessor brought the fourth generation of computers.

They came into existence in 1971.

They were invented by Ted Hoff.

Power consumption was very less.

Thousands of integrated circuits were built to form a single chip.

MICROPROCESSORS

FIFTH GENERATION(PRESENT FIFTH GENERATION(PRESENT AND BEYOND)AND BEYOND)

Fifth generation computers are based on Fifth generation computers are based on artificial intelligence.artificial intelligence.

They are still in development.They are still in development. The use of parallel processing and The use of parallel processing and

superconductors is helping to make artificial superconductors is helping to make artificial intelligence a reality.intelligence a reality.
