Technology / Computers / Transistor: A device composed of semiconductor material that amplifies a signal or opens or closes a circuit. Invented in 1947 at Bell Labs, transistors have become the key ingredient of all digital circuits, including computers. Today's microprocessors contains tens of millions of microscopic transistors. Prior to the invention of transistors, digital circuits were composed of vacuum tubes, which had many disadvantages. They were much larger, required more energy, dissipated more heat, and were more prone to failures. It's safe to say that without the invention of transistors, computing as we know it today would not be possible.

Bipolar Transistor

Technology / Home Audio / Bipolar Transistor: A older but still effectively used transistor type that contains two p or n junctions or diodes between two layers of opposite polarity material (emitter and collector) . In handling large power, most MORE
