Also known as a vacuum tube, an electron tube is a glass tube and/or bulb that looks similar to light bulbs used in house lights today. Electron tubes were used in early computers as on and off switches for digital transmission. Today, electron tubes are no longer used in computers and have been replaced by various types of transistors.
