Detailed explanation-1: -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-2: -1904: British engineer John Ambrose Fleming invents and patents the thermionic valve, the first vacuum tube. With this advance, the age of modern wireless electronics is born.
Detailed explanation-3: -The first generation of computers used vacuum tubes; the second generation of computers used transistors; the third generation of computers used integrated circuits; and the fourth generation of computers used microprocessors.
Detailed explanation-4: -Examples of the first generation computers include ENIAC, EDVAC, UNIVAC, IBM-701, and IBM-650. These computers were large and very unreliable.
Detailed explanation-5: -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.
