Suppose that a disk has 200 cylinders (0-200). The head pointer is currently at 50 and previously at 35. The queue of pending request, in FIFO order is: 60, 190, 40, 125, 15, and 150. The time required to move per cylinder is 6 msec. Starting from the current head position, what is the total seek time needed to satisfy all the pending request for each of the following disk scheduling algorithms? a) FCFS   b) SCAN

A worked answer is on its wayMeanwhile, read the Operating System notes for this topic.
