QUESTION 1

a) Disk requests come into the disk driver for cylinders: 86, 1470, 913, 1774, 948, 1509, 1022, 1750, 130 in that order. The disk has 5000 total cylinders (numbered 0 to 4999) and the disk head positioned over cylinder 143 and previous request was at cylinder 125. What is the sequence of reads and calculate the total distance the read/write head will traverse using Shortest Seek Time First and SCAN algorithms?

b) What are the short comings of shortest seek time first (SSTF) disk scheduling algorithm?

c) What is a bootstrap program, and where is it stored?

Note: Do not write the answer in your handwriting and the answer should be non-replicated from the site.
