Suppose that a disk drive has 1000 cylinders, numbered 0 to 999. The head pointer is currently at cylinder 60. The queue of pending requests is as follows: 130, 150, 78, 600, 350, 420, 540, 145, 930, 20, 880, 690, 890 Starting from the current head pointer, what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests, for the Shortest Seek Time First and C-SCAN algorithms? Also, draw the head movement diagram for calculating the distance?
