COMPUTER FUNDAMENTALS

Detailed explanation-1: -The period 1940 to 1956, roughly considered as the First Generation of Computer. The first generation computers were developed by using vacuum tube or thermionic valve machine. The input of this system was based on punched cards and paper tape; however, the output was displayed on printouts.

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: -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: -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-5: -The first generation computers were used during 1942-1955. They were based on vacuum tubes. Examples of first generation computers are ENIVAC and UNIVAC-1. Vacuum tubes were the only electronic component available during those days.
