(b) The CPU is responsible for processing instructions. One stage of processing instructions is the decode stage.
(i) Identify the two other stages of processing instructions.

The answer to this question is given below in the explanation section.

Explanation:

The CPU is responsible for processing instruction. CPU instruction processing goes through three stages. Fetch, Decode, and Execute.

When the program runs,  program code is copied from secondary storage into main memory. CPU's program counter set to the first instruction of the program stored in memory where the program starts executing.

When a program is being executed, it goes through fetch-decode-cycle. which repeats over and over again until reaching the STOP instruction.

The processor check which next instruction to be executed, then the processor fetches that instruction value from the memory location.  once the instruction being fetched it gets decoded and executed. This instruction processing cycle repeating until the CPU finds a stop instruction.
