Atanasoff and Berry’s design was based on the concept of the electronic digital computer, which had been first proposed by Alan Turing in 1936. Unlike earlier computers, which were based on mechanical switches, Atanasoff and Berry’s design used vacuum tubes to store and process information. This made it possible to program the computer to carry out a range of …
