Question

A computer executes programs in the sequence of:

• A. Decode, Fetch, Execute
• B. Execute, Fetch, Decode
• C. Fetch, Decode, Execute
• D. Store, Fetch, Execute

Answer 1

Answer:

C. Fetch, Decode, Execute

Fetch-Decode-Execute Cycle is the basic operation cycle of a computer. It is the process by which a computer retrieves a program instruction from its memory (fetch), determines what actions the instruction requires (decode), and carries out those actions (execute). It is repeated continuously by the central processing unit, from boot up to when the computer is shut down.
