Is disk scheduling, other than FCFS scheduling, useful in a single-user environment? Explain your answer.
In a single-user environment, the I/O queue usually is blank. Requests generally arrive from a one process for one block or for a sequence of consecutive blocks. In these cases, FCFS is an economical process of disk scheduling.
