In computer architecture, which component of the central processing unit (CPU) directs system operations and manages the fetch-decode-execute cycle?
Answer and explanation
Correct answer: C. Control Unit (CU)
- Step 1: Review the functional modules of the Von Neumann CPU architecture.
- Step 2: The Control Unit (CU) orchestrates the fetch-decode-execute cycle, interpreting machine instructions and generating timing control signals for all other CPU and bus components.
Answer
Control Unit (CU).
Why not the others: The ALU performs arithmetic and logical calculations; the MDR temporarily holds data read from memory; the cache stores instructions for rapid access.
