Questions and Answers

What is the purpose of the CPU scheduler?

  • To prioritize processes based on their resource requirements
  • To handle input/output operations for processes
  • To allocate CPU cores to processes in the ready queue (correct)
  • To manage memory allocation for processes

Which of the following situations does NOT require a CPU scheduling decision?

  • A process switches from running to waiting state (correct)
  • A process terminates
  • A process switches from running to ready state
  • A process switches from waiting to ready state

How can the ready queue be ordered?

  • Based on the arrival time of processes
  • Based on the CPU burst time of processes
  • The text does not specify how the ready queue can be ordered (correct)
  • Based on the priority of processes
