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,
