von-neumann-architecture (1127B)
1 The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC,[1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering. The document describes a design architecture for an electronic digital computer made of "organs" that were later understood to have these components:
2
3 A processing unit with both an arithmetic logic unit and processor registers
4 A control unit that includes an instruction register and a program counter
5 Memory that stores data and instructions
6 External mass storage
7 Input and output mechanisms[1][2]

9 The attribution of the invention of the architecture to von Neumann is controversial, not least because Eckert and Mauchly had done a lot of the required design work and claim to have had the idea for stored programs long before discussing the ideas with von Neumann and Herman Goldstine.[3]
