Suppose a disk has 201 cylinders, numbered from 0 to 200. At some time the disk arm is at cylinder
100, and there is a queue of disk access requests for cylinders 30, 85, 90, 100, 105, 110, 135 and
145. If Shortest-Seek Time First (SSTF) is being used for scheduling the disk access, the request for
cylinder 90 is serviced after servicing ____________ number of requests.

Suppose a disk has 201 cylinders, numbered from 0 to 200. At some time...
Explanation:
SSTF algorithm works by servicing the request that is closest to the current position of the disk arm. In this case, the disk arm is at cylinder 100, and there is a queue of disk access requests for cylinders 30, 85, 90, 100, 105, 110, 135 and 145.
When the algorithm starts, it will service the request for cylinder 100, which is the closest request to the current position of the disk arm. After servicing cylinder 100, the algorithm will select the closest request to it, which is cylinder 90.
Therefore, the request for cylinder 90 is serviced after servicing 2 requests, which are cylinders 85 and 105. So, the answer is 3, as the request for cylinder 90 is serviced after servicing 3 requests, which are cylinders 85, 105, and 145.
Final Answer: 3.
