a component used in electronic devices consisting of three regions of at least two types of a semiconducting material, such as doped silicon, connected to each other and to three electrodes in a conducting path so as to modify the current or voltage in an electronic circuit.

Device made from solid semiconductor material that can amplify audio signals.

An active semiconductor device, usually made of silicon or germanium, having three or more electrodes. The three main electrodes used are the emitter, base, and collector.

An electronic component which is used to regulate the flow of electricity. A transistor has a collector which receives voltage from a source, an emitter which releases the voltage from the collector, and a base which acts as a valve opening and closing the collector-emitter circuit depending on voltage. Electricity only flows in one direction through a transistor.

The on and off switches found inside every single piece of computer equippment, the on and off states on transistors is the language of the computer, binary. Today's advanced CPU's have millions upon million of transistors.

Transistor is the fourth studio album by 311. It was released on August 5, 1997. The album was certified Platinum, having sold over 1 million copies.

Transistor is the seventh studio album by the Norwegian hard rock band TNT. While it kept the alternative feel of Firefly, it was more successful than Firefly, with the song "Just Like God" receiving some radioplay.
