Consider the following disk parameters. There are 16 surfaces, each with 100,000 tracks per surface. The disk rotates at 8800 rounds per minute. Each track consists of 1024 sectors, each of which can store 1024 bytes. 10% of each track is used for gaps. The overhead to move the r/w head to a different cylinder is 1 ms, plus lms to move over 5000 tracks. Using the above information, answer the following questions. (a). What is the disk capacity in GB? (b). If the tracks are located on the outer 1 inch of a 3.5-inch-diameter surface, what is the average bit density (per inch) of a track? (c). Determine the maximum and average seek times. (d). Determine the maximum and average rotational delays. (e). If a disk block consists of 4 sectors, determine the time it takes (in ms) to transfer 16 consecutive blocks from the disk
