Q5. Chapter 11 - Disk Scheduling A disk receives the following track requests: 27, 129, 110, 186, 147, 41, 10, 64, and 120. Assume that the head is currently over track 100 and is moving in the direction of decreasing track number. Using a table similar to Table 11.2, calculate the Average Seek Length for the i) FIFO ii) SSTF iii) SCAN iv) C-SCAN disk scheduling algorithms.

Step 1

We have a list of track requests: 27, 129, 110, 186, 147, 41, 10, 64, and 120. The disk head is currently over track 100 and is moving towards the decreasing track number. We need to calculate the Average Seek Length for four different disk scheduling algorithms: Show more…
