The motive of this article is to give you clear & concise understanding of modern computing, its evolution, and basic principles of it.
It all started in 1940–1945, when the United States and Britain worked independently on creating computers to gain an advantage during the war. By 1951, there was a commercial computer on the market. Information could now be processed and manipulated automatically. Here’s the story of how it all happened.
In 1942, the first all-electronic digital computer, Atanasoff Berry Computer (ABC) was constructed. It was a breakthrough since it used electronic vacuum tubes to perform calculations, rather than wheels or mechanical switches as previous computers did. However, the computer was not re-programmable or general purpose at all.
