Questions and Answers

What is the primary goal of CPU scheduling in a multi-programming environment?

  • To prioritize I/O over CPU processing.
  • To keep the CPU as busy as possible. (correct)
  • To ensure all processes have equal CPU time.
  • To allow user intervention in process execution.
  • Which CPU scheduling algorithm is non-preemptive and selects the next process to run based on arrival time?

  • Priority Scheduling
  • Shortest-Job-First
  • First-Come, First-Served (correct)
  • Round-Robin
  • In the Linux Completely Fair Scheduler, how is the time quantum for a process determined?

  • Based on the nice value of the process. (correct)
  • By a fixed time slice.
  • Based on process ID.
  • Through manual configuration by the system administrator.
