Assume that the average seek time for the hard disk from problem 1 is 8ms (milliseconds), there are 3,000 sectors on each track, and the disk rotates with 12,000 revolutions per minute.
A. Compute the average rotational delay (latency time). Compute the transfer time for 1 sector. Express both times in milliseconds. Then compute the total disk access time required to access 1 sector which is the sum of the three times: the average seek time, the average rotational delay (latency time), and the transfer time for 1 sector. Show your computations.
B. Compute the transfer time for 1200 sectors. Express this time in milliseconds. Then compute the total hard disk access time required to read 1200 sectors which is the sum of the three times: the average seek time, the average rotational delay (which you have already computed in step 2A above), and the transfer time for 1200 sectors. Show your computations.
