Suppose that a disk drive has 6,000 cylinders, numbered 0 to 5999. The drive is currently serving a request at cylinder 2225, and the previous request was at cylinder 5195 (Hint: this indicates the reading head’s moving direction). The queue of pending requests, in FIFO order, is:

5962,2876,5452,1369,3594,5046,866,3269,409,1744

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

1. SSTF


2. SCAN


3. LOOK


4. C-SCAN


5. C-LOOK
