Memory and the stored program concept
Computers as we know them were first built in the 1940s, and two of the early pioneers were Alan Turing and John von Neumann. The von Neumann architecture specifies the basec components of the computer and processor in which a shared memory and bus is used for both data and instructions.
The stored program concept:
Virtually all computers today are built on this principle, and so the general structure as shown in the figure below is sometimes referred to as the von Neumann machine.
How data is stored in computer memory?
Central Processing Unit (CPU)
The scheme of interaction of computer parts
Main memory – stores data and instructions that will be used by the processor.
Name three internal components of a processor.
Describe the Von Neumann model of computer architecture. (5 marks)
