von newmann architecture

• Von Neumann architecture is the design upon which many general purpose computers are based. The key elements of Von Neumann architecture are:

  • data and instructions are both stored as binary digits
  • data and instructions are both stored in primary memory
  • instructions are fetched from memory one at a time and in order (serially)
  • the processor decodes and executes an instruction, before cycling around to fetch the next instruction
  • the cycle continues until no more instructions are available
