Detailed explanation-1: -A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. Although superseded by second-generation transistorized computers, vacuum-tube computers continued to be built into the 1960s.
Detailed explanation-2: -The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.
Detailed explanation-3: -The ENIAC was the first operational electronic general-purpose computer, which stands for Electronic Numerical Integrator and Computer. In ENIAC, 18000 vacuum tubes were used to build it in 1943.
