What is the purpose of the long-term scheduler in a time-sharing system?
What is the purpose of the long-term scheduler in a time-sharing system?
- To perform context switches and save the state of old processes when the CPU switches to a new process
- To control the degree of multiprogramming by selecting which processes should be brought into the ready queue (correct)
- To select which processes should be executed next on the CPU
- To manage the various queues of processes, such as the job queue and device queues
Which of the following best describes the difference between an I/O-bound process and a CPU-bound process?
Which of the following best describes the difference between an I/O-bound process and a CPU-bound process?
- I/O-bound processes spend more time doing I/O than computations, while CPU-bound processes spend more time doing computations than I/O. (correct)
- I/O-bound processes spend more time doing computations, while CPU-bound processes spend more time doing I/O.
- I/O-bound processes have longer CPU bursts, while CPU-bound processes have shorter CPU bursts.
- I/O-bound processes have a higher priority for the CPU scheduler, while CPU-bound processes have a lower priority.
When a CPU switches to a new process, what is the purpose of a context switch?
When a CPU switches to a new process, what is the purpose of a context switch?
- To manage the various queues of processes, such as the job queue and device queues
- To save the state of the old process and load the saved state for the new process (correct)
- To control the degree of multiprogramming by selecting which processes should be brought into the ready queue
- To select which process should be executed next and allocate the CPU to that process
