a) Suppose a disk drive has 200 cylinders. The current position of the R/W head is at cylinder 50 and the previous request was at cylinder 45. The sequence of pending requests is 40,82, 140, 46, 88,…
15- a) Suppose a disk drive has 200 cylinders. The current position of the R/W head is at cylinder 50 and the previous request was at cylinder 45. The sequence of pending requests is 40,82, 140, 46, 88, 170, 197, 135. Starting from current position what is the total number of track movements (distance) for the following disk scheduling algorithms.
- i) SSTF ii. LOOK iii. C-SCAN iv) FCFS
- b) Explain the different attributes of file. Explain the file allocation techniques.
A worked answer is on its wayMeanwhile, read the Operating System notes for this topic.
