Suppose the head of a moving-head disk with 200 tracks numbered 0 to 199 is currently serving a request at track 105 and has just finished a request at track 110. The queue order of outstanding requests in FIFO :order is 40,100,140,5,90,50 ? What is the total number of head movements (in cylinders) for the following disk-scheduling algorithms a) FCFS b) SSTE c) C-SCAN
