8.) [15 pts.] Suppose that a disk drive has 2,000 cylinders, numbered 0 to 1,999. The drive is currently serving a request at cylinder 1010. The queue of pending requests, in FIFO order, is: 1010, 1310, 1950, 800, 200, 750, 1000 Starting from the current head position, what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests for each of the following disk scheduling algorithms: a.) FCFS b.) SSTF (Shortest Seek Time First) c.) SCAN
