Questions and Answers

Which of the following is the main purpose of CPU scheduling in an operating system?

  • To prioritize certain processes over others
  • To ensure all processes get equal CPU time
  • To maximize CPU utilization (correct)
  • To minimize the average waiting time of processes

    • How does the scheduling of small processes like P2 and P3 alongside a large process like P1 impact the overall CPU utilization?

  • It increases CPU utilization by keeping the CPU busy with smaller tasks (correct)
  • It improves CPU utilization by allowing the CPU to switch between processes efficiently
  • It has no impact on CPU utilization as long as the CPU is fully utilized
  • It decreases CPU utilization by increasing the average waiting time

    • Which of the following is a key factor that determines the effectiveness of a CPU scheduling algorithm?

  • The burst time of processes (correct)
  • The priority of processes
  • The number of processes in main memory
  • The arrival time of processes

    • Suppose a CPU scheduling algorithm is designed to prioritize processes based on their arrival time. How would this affect the average waiting time of processes compared to an algorithm that schedules processes based on their burst time?
