Detailed explanation-1: -The vacuum tube is a glass tube with its gas removed, creating a vacuum. Vacuum tubes contain electrodes for controlling electron flow and were used in early computers as a switch or an amplifier.
Detailed explanation-2: -It is used as a switch, amplifier or display screen (CRT). Used as on/off switches, vacuum tubes allowed the first computers to perform digital computations. Although tubes made a comeback in high-end stereo components, they have long since been abandoned for TVs and computer monitors.
Detailed explanation-3: –Lower power consumption: Vacuum tubes consumed less power than relays, which made them more efficient and reduced the amount of heat generated by the circuit.-Greater reliability: Vacuum tubes were more reliable than relays because they had no moving parts that could wear out or fail.
