•William Shockley, John Bardeen, and Walter Brattain demonstrated the first transistor to

press conference in New York Bell Laboratories.

•Prior to the transistor the vacuum tube, which was fragile and required tons of

power•The Transistor is a semiconductor devices that is used to amplify, switch electronic

signals, and electrical power•Composed of semiconductor material with terminal for

connection to an electrical circuit.

•A current applied to one pair of terminals changes the current through another pair of transistors

•Used to amplify the signals

•Transistor paved the way to modern technology and electrical devices, leading to smaller radios, calculators, and computers.•This is why this should be awarded the

Noble Prizehttp : / /en.wik ipedia .org /wik i /Trans istor
