Which CPU scheduling algorithm may cause a low-priority process to starve indefinitely ?

  • A.First Come First Served
  • B.Round Robin
  • C.Priority scheduling
  • D.Shortest Job First
  • E.None of the above

Answer: C

Correct answer: Priority scheduling

Under strict priority scheduling a steady stream of higher-priority arrivals can keep a low-priority process waiting forever. Ageing, which gradually raises the priority of a waiting process, is the usual remedy. Shortest Job First can starve long jobs for the same reason.
