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. But LOOK is nearly as simple to program and will give much better performance when many processes are performing concurrent I/O, like when a Web browser retrieves data in the background whereas the operating system is paging and another application is active in the foreground.
