6. Summary

Another name for the Von Neumann architecture is the stored program computer
A computer architecture is not an actual computer but the idea of how a computer could be built.
The Von Neumann architecture includes program and data loaded into memory
Registers in a CPU includes the Memory Data Register (MDR) and the Memory Address Register (MAR)
The Program Counter contains the the address of the next instruction
The Accumulator holds temporary data whilst processing is underway.
Modern CPUs include a number of extra general purpose registers to make programs more efficient than having a single register needing to contain every temporary data item.
