A certain disk rotates at 5400 revolutions per minute, has 128 tracks each of which is divided into sixteen 512-byte sectors. Assume that there are no gaps between sectors. Given no other information, answer the following questions.
a) What is the maximum possible rotational latency required to get to the beginning of a specified sector?
b) What is the minimum possible rotational latency required to get to the beginning of a specified sector?
c) What is the average rotational latency required to get to any sector?
The following examples will clarify some of these concepts.Example 1Find the average rotational latency if the disk rotates at 20,000 rpm.SolutionThe average latency to the desired data is…
