Show answer & explanation

Correct answer: B

Concept

CPU scheduling separates selection from dispatch. A scheduler chooses the next ready process according to a scheduling policy, while a dispatcher performs the context switch and transfers processor control to the selected process.

Application

The stem asks for the component that hands CPU control to a process after the scheduler has selected it. That operational handoff is performed by the dispatcher.

Contrast

  • A file manager organizes files, directories, storage access, and permissions.

  • A scheduler selects the next ready process according to a scheduling policy.

  • An input/output handler coordinates device requests, interrupts, and data transfer.

Therefore, the required component is the dispatcher.
