8.) 15 pts.]Suppose that a disk drive has 2,000 cylinders, numbered O to 1,999. The drive is currently serving a request at cylinder 1010. The queue of pending requests, in FIFO order, is: 1010, 1210, 1950, 800, 200, 750, 1000 Starting from the current head position, what is the total distance (in disk arm moves to satisfy all the pending requests for each of the following diskt scheduling algorithms cylinders) that the a.)
