Galvin Edition 9 Exercise 10 Question 1 (Page No. 497)

Question

Is disk scheduling, other than $FCFS$ scheduling, useful in a single-user environment ? Explain your answer.

Answer 1

Yes, disk scheduling other than FCFS scheduling can be useful in a single-user environment. SSTF is useful when the data sets are near each other. In the elevator scheduling, we saw that the effects are optimal because it is more efficient than FCFS but unlike SSTF, there are no starvation.
