Select the correct name for: the part of the CPU that performs arithmetic and logical operations.
Difficulty: Medium
About this MCQ
This Medium Computer Architecture MCQ checks one syllabus fact.
The question is: “Select the correct name for: the part of the CPU that performs arithmetic and logical operations.”
The accepted answer is B. ALU. “Select the correct name for: the part of the CPU that performs arithmetic and logical operations.” is answered by ALU (option B). Option A (“Superscalar architecture”) does not match the stem; it is a near-miss used to catch incomplete recall of ALU. Option C (“Register”) does not match the stem; it is a near-miss used to catch incomplete recall of ALU. Remaining alternatives (Control unit) fall outside the same rule and should be eliminated once ALU 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.
