At some time the disk arm is at cylinder 50, and there is a queue of disk access requests for cylinders 4, 34, 10, 7, 19, 73, 2, 15, 6 and 20. Assuming that shortest seek-time first (SSTF) is being used for scheduling the disk access. Calculate the total time taken to satisfy all requests if it takes 1 millisecond to move from one cylinder to adjacent one.20227m
