Question:medium

Consider a disk queue with requests for I/O to blocks on cylinders as 98, 183, 37, 122, 14, 124, 65, 67 and head starts at 53. What are the total head movements for FCFS and SSTF algorithms?

Show Hint

SSTF (Shortest Seek Time First) always services the closest pending request and usually performs better than FCFS.
