ABSTRACT
The first electronic computer was invented in 1946 and used vacuum tubes and relays to perform its operations. Called the E N I A C , its programs were hardwired to execute commands o f up to 5000 additions and subtractions in one second. Von Neumann then conceptualized an architecture that could store programs instead o f having to hardwire them. From this technology M . V . Wikes implemented the EDSAC, the first operational stored-memory computer.
