Questions and Answers

What is the primary goal of the process scheduling system?

  • To maximize CPU idle time
  • To prioritize one process over others
  • To delay process swapping as much as possible
  • To minimize response time for all programs (correct)

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)
  • Final CPU Swap
  • Fastest CPU Scheduling
  • Flexible Core System
