Quizplus · Accepted Answer

The bus interface unit (BIU) is responsible for managing the flow of data in and out of the CPU. It interacts with other computer components through the system bus and coordinates memory read and write operations. The control unit, prefetch unit, and decode unit are internal components of the CPU that work together to execute instructions but do not directly handle the input and output of data.
