Test: Drilling Down: How the Processor Processes - Year 9 MCQ

The machine cycle includes fetch, decode, execute, and store. Connect is not a stage in the machine cycle.

During the fetch stage of the instruction cycle, the CPU retrieves instructions from the computer’s memory.

During the decode stage, the CPU translates the fetched instruction into a form it can understand, as outlined in the content’s description of the instruction cycle.

The fetch-execute cycle involves retrieving an instruction from memory (fetch), decoding it to understand what needs to be done (decode), executing the instruction (execute), and storing the result in memory or a register (store).

The CPU’s instruction set includes commands for arithmetic operations (e.g., addition, subtraction), logic operations (e.g., AND, OR), and data movement (e.g., between registers and memory), as described in the content under "Instruction Sets and Cycles."

The final stage of the CPU’s instruction cycle is the store stage, where the CPU writes the result of the executed instruction back to memory or a register, as described in the content under "Instruction Cycle."
