von neuman machine :
A von Neumann machine is a model for a computing machine that 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. John von Neumann helped to create the model as an example of a general-purpose computing machine.
A von Neumann architecture machine, designed by physicist and mathematician John von Neumann (1903–1957) is a theoretical design for a stored program computer that serves as the basis for almost all modern computers.
