1.1 First Generation Computers

First Generation Computers

Both in look and performance, the first generation of todays computers showed little similarity to modern computers. The first generation of computers, which occurred between 1940 and 1956, were incredibly enormous. The core functions of computers at the time were not complex. These earliest machines used magnet drums for storage and vacuum tubes as switches and amplifiers. The vacuum tubes were primarily responsible for the machines’ vast size and enormous heat output. Despite the presence of huge cooling equipment, these computers generated so much heat that they frequently overheated. Also used by the first era of computers was machine language, a very basic programming language.
