Q. Is disk scheduling except FCFS scheduling useful in a single-user environment? describe your answer.
Answer: In a single-user environment the I/O queue typically is empty. Requests in general arrive from a single process for one block or for a sequence of consecutive blocks. In these cases the FCFS is an economical method of disk scheduling. However LOOK is nearly as easy to program and will give much better performance when multiple processes are performing concurrent I/O such as when a Web browser retrieves data in the background while the operating system is paging as well as another application is active in the foreground.
