1.      What are the factors that contribute to the delay for a magnetic disk read or write?

Solution

Three primary factors that affect the time required to read/write requested
data from the disk into memory:
A) Seek time :
Time for the appropriate I/O head to reach the desired track.

B) Latency:
Time for the appropriate sector to rotate to the I/O head.

C) Transfer time:
Time for the data to be read to move past the I/O head.
