Question

Quizplus · Accepted Answer

Instruction processing consists of two main steps: fetching the instruction from memory and then executing it. These steps are commonly referred to as the fetch-execute cycle. Therefore, option A (fetch and execute) is the best choice. Option B is incorrect because it combines the two steps into one, and option C is incorrect because it assumes that every instruction results in a halt (which is not always the case). Option D is also incorrect because it does not specify what happens to the instruction after it is fetched.
