What scheduling algorithm allows processes that are logical runnable to be temporarily suspended?

  • A.preemptive scheduling
  • B.non-preemptive scheduling
  • C.FIFO
  • D.FCFS

Answer: A

Correct answer: preemptive scheduling

Under preemptive scheduling the operating system may take the processor from a process that is still able to run - when its time slice expires or a higher-priority process becomes ready - suspending it temporarily and resuming it later. Non-preemptive scheduling waits for the process to block or finish.
