About this MCQ
This Hard Computer Architecture MCQ checks one syllabus fact.
The question is: “What is the function or purpose of Branch prediction?”
The accepted answer is A. A CPU performance technique that guesses the outcome of a conditional instruction before it is known.. A CPU performance technique that guesses the outcome of a conditional instruction before it is known is the fact required by What is the function or purpose of Branch prediction option A Option B The number of bits a processor can handle or transfer in a single operation does not match the stem it is a near-miss used to catch incomplete recall of A CPU performance technique that guesses the outcome of a conditional instruction before it is known Option C The basic unit of time in which a single simple operation of a CPU can occur does not match the stem it is a near-miss used to catch incomplete recall of A CPU performance technique that guesses the outcome.
- A. A CPU performance technique that guesses the outcome of a conditional instruction before it is known. ✓
- B. The number of bits a processor can handle or transfer in a single operation.
Why not B: “The number of bits a processor can handle or transfer in a single operation.” is not correct. The accepted answer is A. A CPU performance technique that guesses the outcome of a conditional instruction before it is known.. A CPU performance technique that guesses the outcome of a conditional instruction before it is known is the fact required by What is the function or purpose of Branch prediction op
- C. The basic unit of time in which a single, simple operation of a CPU can occur.
Why not C: “The basic unit of time in which a single, simple operation of a CPU can occur.” is not correct. The accepted answer is A. A CPU performance technique that guesses the outcome of a conditional instruction before it is known.. A CPU performance technique that guesses the outcome of a conditional instruction before it is known is the fact required by What is the function or purpose of Branch prediction op
- D. Another term for the sequence of fetching, decoding, and executing a single CPU instruction.
Why not D: “Another term for the sequence of fetching, decoding, and executing a single CPU instruction.” is not correct. The accepted answer is A. A CPU performance technique that guesses the outcome of a conditional instruction before it is known.. A CPU performance technique that guesses the outcome of a conditional instruction before it is known is the fact required by What is the function or purpose of Branch prediction op
Correct answer
A. A CPU performance technique that guesses the outcome of a conditional instruction before it is known.
Explanation
