TRANSISTOR
A transistor is a semiconductor
device
used to amplify and switch electronic signals and electrical
power.
It is composed of semiconductor material with at least three
terminals for connection to an external circuit. A voltage or current applied to one pair of the
transistor's terminals changes the current through another pair of terminals.
Because the controlled (output) power can be higher than the controlling
(input) power, a transistor can amplify a signal. Today, some
transistors are packaged individually, but many more are found embedded in integrated
circuits.The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Following its development in the early 1950s, the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things.
