Concept explainers
a.
Explanation of Solution
Given:
Given that the disk drive has the following features:
Number of surfaces = 4
Tracks per surface = 1024
Sectors per track = 128
Bytes per sector = 512 bytes
Seek time = 5ms
Rotational speed = 5000rpm
To find: Capacity of the drive
Solution:
The capacity of the drive is manipulated by multiplying number of surfaces, tracks per surface, sectors per track and bytes per sector.
b.
Explanation of Solution
Given:
Given that the disk drive has the following features:
Number of surfaces = 4
Tracks per surface = 1024
Sectors per track = 128
Bytes per sector = 512 bytes
Seek time = 5ms
Rotational speed = 5000rpm
To find: Access time
Solution:
The summation of rotational delay and seek time is called access time.
Rotational delay =
c.
Explanation of Solution
Faster disk:
Access time is important in order to find the faster disk. The slower the access time, the fastest the disk will be...
