Hardware

The physical elements of a system, in contrast to software.

Once Alan Turing had described the theoretical concept of a Universal Machine in the 1930s it was only a matter of time (and funding) before real hardware was built. The architecture described in Turing paper became the basis for the first true computers (built secretly for decoding German "Enigma" codes) and, following a visit by Turing to John Von Neuman during the war, the first publicly described computers. This same architecture has been the basis for almost all subsequent computer systems.
