Von Neumann Architecture

What is Von Neumann Architecture?

A computer architecture in which program instructions and the data they operate on are held together in the same memory and are accessed using the same addresses, and in which the CPU, memory and input/output components communicate over buses; instructions are fetched and executed one after another in address order unless the flow of control changes.

This definition is part of the Hardware chapter in Cambridge O Level Computer Science.
