About this MCQ

This Hard Computer Architecture MCQ checks one syllabus fact.

The question is: “A classification of computer architectures based on the number of instruction and data streams they can process simultaneously. What is this concept called?”

The accepted answer is C. Flynn's taxonomy. “A classification of computer architectures based on the number of instruction and data streams they can process simultaneously. What is this concept called” is answered by Flynn's taxonomy (option C). Option A (“Clock cycle”) does not match the stem; it is a near-miss used to catch incomplete recall of Flynn's taxonomy. Option B (“Von Neumann bottleneck”) does not match the stem; it is a near-miss used to catch incomplete recall of Flynn's taxonomy. Remaining alternatives (Microarchitecture) fall outside the same rule and should be eliminated once Flynn's taxonomy 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. Clock cycle
Why not A: “Clock cycle” is not correct. The accepted answer is C. Flynn's taxonomy. “A classification of computer architectures based on the number of instruction and data streams they can process simultaneously. What is this concept called” is answered by Flynn's
B. Von Neumann bottleneck
Why not B: “Von Neumann bottleneck” is not correct. The accepted answer is C. Flynn's taxonomy. “A classification of computer architectures based on the number of instruction and data streams they can process simultaneously. What is this concept called” is answered by Flynn's
