1. Is disk scheduling, other than FCFS scheduling, useful in a single-user environment? Explain your answer.
2. Explain why SSTF scheduling tends to favor middle cylinders over the innermost and outermost cylinders.
3. Why is rotational latency usually not considered in disk scheduling? How would you modify SSTF, SCAN, and C-SCAN to include latency optimization?
4. Why is it important to balance file-system I/O among the disks and controllers on a system in a multitasking environment?
5. What are the tradeoffs involved in rereading code pages from the file system versus using swap space to store them?
6. Is there any way to implement truly stable storage? Explain your answer.
