b) Consider a disk queue with requests for I/O to blocks on cylinders 108, 193, 51, 132,  24, 134, 75, 77. The head is initially at cylinder number 63. The cylinders are  numbered from 0 to 199.  Find out the total head movements using the following algorithms a) First Come-First Serve (FCFS) b) Shortest Seek Time First (SSTF) c) Elevator (SCAN) d) Circular LOOK (C-LOOK)b) Consider a disk queue with requests for I/O to blocks on cylinders 108, 193, 51, 132, 24, 134, 75, 77.
