During the fetch-decode-execute cycle the CPU:
A. Fetches an instruction, decodes it, then executes it, and repeats✓ 答案
B. Only stores files on the secondary storage
C. Always skips the decoding stage
D. Sends the result straight to the printer
解說
The instruction cycle repeats: fetch the next instruction from memory, decode what it means, execute it. Only then does the CPU move on, which is why a long program takes many cycles.
