Second Generation
computers were developed during

1956 to 1965

Second generation
computers used transistors

as their main electronic component. Transistor was invented by Bell Lab

Scientists John Burdeen, Walter Brattain and

William Shockley in 1947 and won the Nobel Prize in 1956 but it was not used

in computers till 1956. The second generation continued until

the implementation of IC chips invented by Jack Kilby

in Texas Instruments in 1958.
