The term Von Neumann machine has two seperate meanings. Both meanings are based on the work of John von Neumann. John von Neumann in the 1940s. ...

1. A conceptual model of a computer architecture which uses a single storage structure to hold both the set of instructions on how to perform the computation and the data required or generated by the computation. See Von Neumann architecture. There is some debate as to whether it is accuarate or fair that the arcitecture be named after John von Neumann, however. See the article John von Neumann.
2. A type of machine or system that can replicate itself. The concept was first explored rigourously by John von Neumann, who called them "Universal Constructors" (see Clanking replicator). See: Von Neumann probes, and molecular nanotechnology for specific proposed technologies which implement the concept of the replicating Von Neumann machine.

Computer architecture is the theory behind the design of a computer. ... The term von Neumann architecture refers to a computer design model that uses a single storage structure to hold both instructions and data. ... John von Neumann in the 1940s. ... A clanking replicator is an artificial self-replicating system that relies on conventional large-scale technology and automation. ... A von Neumann probe is a specific example of a hypothetical concept based on the work of Hungarian-born American mathematician and physicist John von Neumann. ... It has been suggested that Molecular engineering be merged into this article or section. ...
