Part l: Disk Access Consider a hard disk with the following characteristics: Average seek time: 5ms Average rotational delay: 3ms Page transfer time: 0.04ms Assume the disk has one platter with two surfaces Question 1(5 points) Estimate the time to read a list of 150 pages from disk. where the pages are randomly distributed across the disk. Question 2. (5 points) Estimate the time to read a list of 150 pages from disk, where the pages are randomly distributed in tracks of a single cylinder. Question 3. (5 points) Estimate the time to read a list of 150 pages from disk, where the pages are arranged consecutivelv in tracks of a single cvlinder. Question 4. (5 point) Suppose we don't care about the order in which the 150 pages are read. Suggest how to speed up the times for Questions 1 and 2 above
