Detailed explanation-2: -The ENIAC. The Electronic Numerical Integrator and Computer, also known as the ENIAC, was the first computer that would use the vacuum tube.
Detailed explanation-3: -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.
