Document Summary
A circuit is a. closed path followed or capable of being followed by an electric current. Vacuum tubes need wire circuits inside them to facilitate the flow of electrons. A transistor is a tiny electronic switch that can be turned "on" or "off" millions of times/second. Transistors from part of an integrated circuit embedded on a. single silicon chip. Silicon: a. semiconductor made of clay and sand. Semiconductor: a material whose electrical properties are intermediate between a good conductor and a non-conductor of electricity. Perfect under layer for highly conductive, complex circuits. Chip: a tiny piece of silicon that contains millions of micro miniature integrated electronic circuits. Miniaturization: microchips: store and process data in electronic devices. Microprocessors: the miniaturized circuitry of an entire computer processor on a single chip. Contain the central processing unit (cpu), which processes data into information. System unit: the case that contains the computer"s electronic components used to process data.
