Question 54 |
Which of the following statement(s) is/are correct in the context of CPU scheduling?
Implementing preemptive scheduling needed hardware support. | |
Turnaround time includes waiting time | |
Round-robin policy can be used even when the CPU time required by each of the processes is not known apriori. | |
The goal is to only maximize CPU utilization and minimize throughput. |
Question 54 Explanation:
- True. Preemptive scheduling needs hardware support such as a timer
- True. Turnaround time = Burst time + Waiting time
- True, RR assigns qunatume to each process equally. Hence, it is not required to know burst size apriori
- False. Maximize CPU utilization and throughput, and minimize waiting time etc.
