Quizplus · Accepted Answer

The role of the prefetch unit is to predict and retrieve data and instructions ahead of time, helping to avoid delays in processing. The control unit is responsible for controlling the overall operation of the CPU, the floating-point unit performs mathematical calculations involving decimal numbers, and the arithmetic/logic unit performs basic arithmetic and logical operations. None of these options are directly related to prefetching data.
