PreviousSuppose a disk has 100 cylinders, numbered from 0 to 99. At some time the disk arm is at cylinder 50, and there is a queue of disk access requests for cylinders 4, 34, 10, 7, 19, 73, 2, 15, 6 and 20. Assuming that shortest seek-time first (SSTF) is being used for scheduling the disk access. Calculate the total time taken to satisfy all requests if it takes 1 millisecond to move from one cylinder to adjacent one.NextConsider the virtual page reference string 0, 4, 8, 20, 24, 36, 44, 12, 68, 72, 80, 84, 28, 32, 88, 92 on a demand paged virtual memory system running on computer system that has main memory of size 4 page frames which one initially empty. The CPU uses LRU page replacement policy. (i) How many page faults does this sequence cause? (ii) What are the page numbers of the pages present in the main memory at the end of the sequence?
