Hungarian-born John von Neumann (1903-1957), an internationally renowned mathematician, promoted a theoretical design for a computer in the 1940s. He envisioned the stored program concept ...

Tom Hackett traces the evolution of the von Neumann computer architecture through a series of adaptations intended to bypass processing bottlenecks that appeared as more and more demands were placed ...

program counter (PC) - holds the memory address of the next instruction to be fetched from primary memory memory address register (MAR) - holds the address of the current instruction that is to be ...

The registers and key elements of the Von Neumann architecture all play a part in how an instruction is processed in the fetch-decode-execute cycle.
