About this MCQ
This Hard Computer Architecture question asks: The following statement describes a specific concept. What is it called? a layered arrangement of progressively larger and slower memory levels used to balance speed and cost. The correct choice is C. Cache memory hierarchy. 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. Control unit
Why not A: “Control unit” does not fit this question. The answer is Cache memory hierarchy.
- B. Superscalar architecture
Why not B: “Superscalar architecture” does not fit this question. The answer is Cache memory hierarchy.
- C. Cache memory hierarchy ✓
- D. Clock speed
Why not D: “Clock speed” does not fit this question. The answer is Cache memory hierarchy.
Correct answer
C. Cache memory hierarchy
Explanation
Cache memory hierarchy (option C) is the accepted answer to “The following statement describes a specific concept. What is it called? a layered arrangement of progressively larger and slower memory levels used to balance speed and cost.”. Option A (Control unit) does not fit this question. Option B (Superscalar architecture) does not fit this question. Option D (Clock speed) does not fit this question. For this Computer Architecture question, the accepted answer is Cache memory hierarchy.
