Identify the correct definition of Program counter.
Difficulty: Medium
About this MCQ
This Medium Computer Architecture MCQ checks one syllabus fact.
The question is: “Identify the correct definition of Program counter.”
The accepted answer is B. A CPU register that holds the memory address of the next instruction to be executed.. Identify the correct definition of Program counter is answered by A CPU register that holds the memory address of the next instruction to be executed option B Option A A technique used in an instruction to specify how the operand's memory address is determined does not match the stem it is a near-miss used to catch incomplete recall of A CPU register that holds the memory address of the next instruction to be executed Option C 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 register that holds the memory address of the next instruction to be executed.
- A. A technique used in an instruction to specify how the operand's memory address is determined.
Why not A: “A technique used in an instruction to specify how the operand's memory address is determined.” is not correct. The accepted answer is B. A CPU register that holds the memory address of the next instruction to be executed.. Identify the correct definition of Program counter is answered by A CPU register that holds the memory address of the next instruction to be executed option B Option A A technique
- B. A CPU register that holds the memory address of the next instruction to be executed. ✓
- C. The number of bits a processor can handle or transfer in a single operation.
Why not C: “The number of bits a processor can handle or transfer in a single operation.” is not correct. The accepted answer is B. A CPU register that holds the memory address of the next instruction to be executed.. Identify the correct definition of Program counter is answered by A CPU register that holds the memory address of the next instruction to be executed option B Option A A technique
- D. A CPU performance technique that guesses the outcome of a conditional instruction before it is known.
Why not D: “A CPU performance technique that guesses the outcome of a conditional instruction before it is known.” is not correct. The accepted answer is B.
