Von Neumann Architecture and Non-Von Neumann Architecture of Computers
In the 1946 paper, written with Arthur W. Burks and Hermann H. Goldstine, titled "Preliminary Discussion of the Logical Design of an Electronic Computing Instrument," Von Neumann outlined the basis for the general computing device and the ideas in it were profound and they had a great impact on the subsequent development of such machines.
Von Neumann's design led eventually to the construction of the EDVAC computer in 1952.
Von Neumann described in his "Preliminary Discussion" the general-purpose computing machine as one containing four main "organs." These are identified as relating to arithmetic, memory, control, and connection with the human operator. They represent today the arithmetic logic unit, the control unit, the memory, and the input-output devices.
