Von Neumann Architecture simply refers to the type of computer setup that we have always talked about. Some of the key features are:
- Data and instructions are stored in the same memory (RAM).
- The CPU executes one instruction at a time.
- Registers store actively used data (Accumulator, Memory Address Register (MAR – stores the location of the data needed), Current Instruction Register (CIR – stores the location of the next intruction to be executed)).
This website provides more detail about Vonn Neumann and is a great resource for other topics too.
