Question
Disk requests come to disk driver for cylinders 10, 153, 34, 90, 120, 205, 319, 256 and 400 in that order at a time when the disk drive is reading from cylinder 99. The cylinders are numbered from 0 to 499. Compute the total head movement incurred while servicing these requests if the disk arm scheduling algorithm is first-come-first-serve.
