Identify the correct concept described as: a CPU design that can execute more than one instruction during a single clock cycle.
Difficulty: Hard
About this MCQ
This Hard Computer Architecture MCQ checks one syllabus fact.
The question is: “Identify the correct concept described as: a CPU design that can execute more than one instruction during a single clock cycle.”
The accepted answer is C. Superscalar architecture. “Identify the correct concept described as: a CPU design that can execute more than one instruction during a single clock cycle.” is answered by Superscalar architecture (option C). Option A (“Control unit”) does not match the stem; it is a near-miss used to catch incomplete recall of Superscalar architecture. Option B (“Instruction set architecture (ISA)”) does not match the stem; it is a near-miss used to catch incomplete recall of Superscalar architecture. Remaining alternatives (RISC) fall outside the same rule and should be eliminated once Superscalar architecture is identified. Computer Architecture questions of this type reward precise definitions rather than approximate associations. Computer Architecture recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
- A. Control unit
Why not A: “Control unit” is not correct. The accepted answer is C. Superscalar architecture. “Identify the correct concept described as: a CPU design that can execute more than one instruction during a single clock cycle.” is answered by Superscalar architecture (option C)
- B. Instruction set architecture (ISA)
Why not B: “Instruction set architecture (ISA)” is not correct. The accepted answer is C. Superscalar architecture. “Identify the correct concept described as: a CPU design that can execute more than one instruction during a single clock cycle.” is answered by Superscalar architecture (option C)
- C. Superscalar architecture ✓
- D. RISC
