State what is meant by the stored program concept in the Von Neumann model of a computer system？

• Temporarily store data that is being used by the CPU.

• To store a value that is added to an address to give another address.

• Instructions and data are stored in the same memory space / in main memory.

• to store flags which are set by events // from the results of arithmetic and logic operations and interrupt flags.

Describe the purpose of the Control Unit in a CPU?

• to coordinate / synchronise the actions of other components in the CPU

• By creating timing signals to synchronise operations.

• It is performs arithmetic operations and logical comparisons.

• It is a high-speed, temporary storage unit that holds data and instructions when they are fetched from the main memory and are awaiting processing by the CPU.
