A three terminal semiconductor amplifying device, the fundamental component of most active electronic circuits, including digital electronics. The transistor was invented on 1947-12-23 at Bell Labs.

There are two kinds, the bipolar transistor (also called the junction transistor), and the field effect transistor (FET).

Transistors and other components are interconnected to make complex integrated circuits such as logic gates, microprocessors and memory.
