The main function of the dispatcher (the portion of the process scheduler) is

  • A.swapping a process to the disk
  • B.assigning ready process to the CPU
  • C.suspending some of the processes when the CPU load is high
  • D.bring processes from the disk to the main memory

Answer: B

Correct answer: assigning ready process to the CPU

The scheduler decides which process should run next; the dispatcher performs the handover - switching context, restoring the chosen process’s registers and program counter, and giving it the processor. Swapping and paging are the memory manager’s work.
