About this MCQ
This Easy Computer Architecture question asks: Which of the following best names the concept in which the rate at which a processor executes instructions, measured in cycles per second? The correct choice is B. Clock speed. 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. ALU
Why not A: “ALU” does not fit this question. The answer is Clock speed.
- B. Clock speed ✓
- C. Cache memory hierarchy
Why not C: “Cache memory hierarchy” does not fit this question. The answer is Clock speed.
- D. Parallel processing
Why not D: “Parallel processing” does not fit this question. The answer is Clock speed.
Correct answer
B. Clock speed
Explanation
Clock speed is the term that matches “Which of the following best names the concept in which the rate at which a processor executes instructions, measured in cycles per second” (option B). Option A (ALU) does not fit this question. Option C (Cache memory hierarchy) does not fit this question. Option D (Parallel processing) does not fit this question. For this Computer Architecture question, the accepted answer is Clock speed.
