Difficulty: Hard
About this MCQ
This Hard Computer Architecture question asks: Which term refers to the set of instructions a processor can execute, defining the interface between hardware and software? The correct choice is A. Instruction set architecture (ISA). 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. Instruction set architecture (ISA) ✓
- B. Parallel processing
Why not B: “Parallel processing” does not fit this question. The answer is Instruction set architecture (ISA).
- C. Superscalar architecture
Why not C: “Superscalar architecture” does not fit this question. The answer is Instruction set architecture (ISA).
- D. Bus
Why not D: “Bus” does not fit this question. The answer is Instruction set architecture (ISA).
Correct answer
A. Instruction set architecture (ISA)
