  • Which scheduling category involves the operating system favoring another process over the currently executing one?

  • First Come First Serve (FCFS)
  • Pre-emptive Scheduling (correct)
  • Non Pre-emptive Scheduling
  • Shortest Job First (SJF)
  • What does FCFS stand for in the context of process scheduling?

  • First Come First Serve (correct)
