FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -The era of first generation computer was 1946-1959.

Detailed explanation-3: -The First Generation ( 1945-1955 ): Vacuum Tubes and Plugboards. Digital computers were not constructed until the second world war. Calculating engines with mechanical relays were built at that time. However, the mechanical relays were very slow and were later replaced with vacuum tubes.

Detailed explanation-4: -Introduction: 1946-1959 is the period of first generation computer. J.P.Eckert and J.W. Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated And Calculator”.

Detailed explanation-5: -ENIAC (Electronic Numerical Integrator and Calculator): It was built in 1946 at the University of Pennsylvania, (USA, by John Eckert and John Mauchly.
