Q1➡| A magnetic disk has 100 cylinders, each with 10 tracks of 10 sectors. If each sector contains 128 bytes, what is the maximum capacity of the disk in kilobytes?
Q3➡| Consider the disk which has average seek time of 32 ns and rotational rate of 360 rpm(round per minute), Each track of the disk has 512 sectors, each of size 512 bytes. What is the data transfer rate?
Q4➡| A hard disk system has the following parameters Number of track = 500 Number of sectors/track = 100 Number of bytes/sector = 500 Time taken by the head to move from one track to adjacent track = 1 ms Rotation speed = 600 rpm What is the average time taken for transferring 250 bytes from the disk?
Q7➡| Consider a hard disk with 16 recording surfaces (0-15) having 16384 cylinders (0-16383) and each cylinder contains 64 sectors (0-63). Data storage capacity in each sector is 512 bytes. Data are organized cylinder-wise and the addressing format is . A file of size 42797 KB is stored in the disk and the starting disk location of the file is <1200, 9, 40>. What is the cylinder number of the last sector of the file, if it is stored in a contiguous manner?
Q8➡| Consider a typical disk that rotates at 15000 rotations per minute (RPM) and has a transfer rate of 50×106 bytes/sec. If the average seek time of the disk is twice the average rotational delay and the controller’s transfer time is 10 times the disk transfer time, the average time (in milliseconds) to read or write a 512-byte sector of the disk is ________.
