Scheduling is

  • A.allowing jobs to use the processor
  • B.unrelated to performance consideration
  • C.not required in uniprocessor systems
  • D.the same regard-less of the purpose of the system

Answer: A

Correct answer: allowing jobs to use the processor

Scheduling is deciding which of the ready jobs gets the processor and for how long. It is central to performance - throughput, turnaround and response time all depend on it - it is needed on a uniprocessor precisely because there is only one processor to share, and the policy chosen depends on what the system is for.
