Question

Which of the following may operating system process/thread schedulers attempt to optimize?

A) CPU Utilization: Percent of time that the CPU is running threads

B) CPU Throughput: Number of completed “operations” per second.

C) Turnaround time: Process end time – Process start time.

D) Response time: Minimize total time process waits while ready to run

E) Waiting time: Minimize total time process spends not ready to run

F) Efficiency: Conserve power or other resources

G) Latency: Minimize (or standardize) process response times

H) Fairness: Distribute resources to processes equitably

1. All but H

2. Only H

3. All of them

4. All but B

Explanation / Answer

All options are correct but option b is not 100% correct as CPU throughput is amount of work done in a given time unit, it is not necessary that it will complete some operations in that given time unit.

Hence option 4 seems to be more appropriate option.
