FUNDAMENTALS OF COMPUTER

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 Although superseded by second-generation transistorized computers, vacuum-tube computers continued to be built into the 1960s.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 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-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. And, it was built at the University of Pennsylvania’s Moore School of Engineering with government funds.

Detailed explanation-4: -A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.

Detailed explanation-5: -vacuum tubes are known as first-generation computers.
