of the Transistor
device composed of semiconductor material that amplifies a signal or opens
or closes a circuit, transistors have become the major componet in all
digital circuits, including computer microprocessors which now contain
millions of microscopic size transistors. Prior to transistors, digital
circuits used vacuum
tubes which had many disadvantages, they were larger, used more energy,
and created more heat.
