About this MCQ
This Medium Computer Architecture question asks: What is Control unit primarily used for? The correct choice is C. The component of the CPU that directs the operation of the processor by interpreting instructions.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Computer Architecture items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Computer Architecture so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Computer Architecture item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A small, extremely fast storage location within the CPU used to hold data during processing.
Why not A: “A small, extremely fast storage location within the CPU used to hold data during processing.” does not fit this question. The answer is The component of the CPU that directs the operation of the processor by interpreting instructions..
- B. The part of the CPU that performs arithmetic and logical operations.
Why not B: “The part of the CPU that performs arithmetic and logical operations.” does not fit this question. The answer is The component of the CPU that directs the operation of the processor by interpreting instructions..
- C. The component of the CPU that directs the operation of the processor by interpreting instructions. ✓
- D. The rate at which a processor executes instructions, measured in cycles per second.
Why not D: “The rate at which a processor executes instructions, measured in cycles per second.” does not fit this question. The answer is The component of the CPU that directs the operation of the processor by interpreting instructions..
