Question 1.
What is seek time?
Show hintHide hint
Think about the movement of the read/write head.
Question 2.
Define rotational latency.
Show hintHide hint
Consider the time spent waiting for the correct part of the disk to spin into place.
3Question 3.
What does seek time refer to in disk operations?
- Time to access a sector
- Time to move the head to the correct track
- Time for disk to spin around
Show hintHide hint
Consider the head movement process in retrieval.
4Question 4.
True or False: Zoning helps in reducing wasted space on hard disks.
- True
- False
Show hintHide hint
Think about how data organization affects usage.
Question 5.
A hard disk operates at a rotational speed of 7200 RPM. Calculate the average rotational latency. How would this latency change if the disk speed is increased to 15000 RPM?
Show hintHide hint
Remember to convert RPM to revolutions per second first.
Question 6.
Discuss the impact of varying block sizes on the overall performance of a hard disk in terms of access speed and space efficiency. Provide examples.
Show hintHide hint
Consider the trade-off between speed and space conservation.
