capacity of a track

Exercise 9.4 If you have a large file that is frequently scanned sequentially, explain how you would store the pages in the file  on a   disk.

 

Exercise 9.5 Consider a disk with a sector size of 512 bytes,  2000  tracks  per  surface,  50 sectors  per track,  five  double-sided  platters,  and  average  seek  time  of 10 msec.

 

1.    What is the capacity of a track in bytes? What is the capacity of each surface? What is the capacity of the disk?

2.     How many cylinders does the disk have?

 Give  examples of valid  block sizes.   Is  256  bytes a  valid  block size?  2048?    51,200?

4.     If the disk platters rotate at 5400 rpm (revolutions per minute), what is the maximum rotational delay?

5.    If one track of data can be transferred per revolution, what is the transfer rate?
