Disks
Consider a magnetic disk containing 400 sectors per track. An application needs to read 100 randomly scattered sectors for loading the libraries at start up. Reading each sector requires exactly one disk access. The average seek time of the disk to a random location is ... Rotational speed of the disk is 6000 rpm. How long does it take to load libraries at start up to run the application?

Operating System FIle Systems Question
How long does it take to load a 64Kbytes Program from a disk whose Average Seek time is 30 ms Rotation time is 20 ms, Track Size is 32 Kbytes, Page Size is 4 Kbytes . Assume that Pages of the program are distributed randomly around the disk. What will be the % saving in time if 50% of the Pages of the program are Contiguous?
