The transistor is the fundamental electronic component active electronics used primarily as a controlled switch and amplification, but also to stabilize a voltage signal modulation and many other uses. A transistor is a semiconductor device with three active electrodes, which controls a current (or voltage) on an electrode-collector outputs for the bipolar transistor and the drain of a field effect transistor, with an input electrode, the base of a bipolar transistor and the gate to a field effect transistor. The term comes from English transistor transconductance varistor (variable resistor transconductance). It was voted by a steering committee of 26 people at Bell Labs May 28, 1948, memo 48-130-10 - among the names put forward include: semiconductor triode, surface states triode, crystal triode, solid triode, iotatron, transistor. For commercial reasons, it was a short name, unequivocally with the technology of electron tubes. Transistor was chosen. By metonymy, the term also refers to transistor radios equipped with transistors
