Concept explainers
a.
Explanation of Solution
Given:
Given that the disk drive has the following features:
Number of surfaces = 6
Tracks per surface = 953
Sectors per track = 256
Bytes per sector = 512 bytes
Seek time = 6.5ms
Rotational speed = 5400rpm
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 = 6
Tracks per surface = 953
Sectors per track = 256
Bytes per sector = 512 bytes
Seek time = 6.5ms
Rotational speed = 5400rpm
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:
“Yes”, this disk faster than the disk that was specified in Exercise 30 because, the access time “12.66ms” in “Exercise 30” is slower than the access time “12...
