Briefly explain the following: (i) Why rotational latency is usually not considered in disk scheduling? How would you modify
SSTF, SCAN, and C-SCAN to include latency optimization?
(ii) Why must the bit map for file allocation be kept on mass storage, rather than in main memory?
(iii)Consider a system that supports the strategies of contiguous, linked, and indexed allocation.
What criteria should be used in deciding which strategy is best utilized for a particular file?
(iv)How file allocation table (FAT) works? Explain with the help of diagram.
(v) What is the difference between deadlock prevention and deadlock avoidance? What category
does Bankers algorithm fall in and why?
