Question 1.
What does 'constant angular velocity' mean in relation to hard disks?
Show hintHide hint
Think about how the speed affects data retrieval.
Question 2.
List the three components needed to address data on a hard disk.
Show hintHide hint
Consider how you would differentiate data storage spots.
3Question 3.
What is the meaning of constant angular velocity in hard disks?
- The disks rotate at varying speeds.
- The disks rotate at the same speed throughout.
- It determines data integrity.
Show hintHide hint
Think about how this might simplify data retrieval.
4Question 4.
True or False: Seek time is the time needed to move the head to the correct track.
- True
- False
Show hintHide hint
Recall the importance of positioning for efficient data access.
Question 5.
Design a simple simulation model for a hard disk controller that demonstrates data retrieval from different tracks and the effect of seek time and rotational delay on efficiency.
Show hintHide hint
Consider the components of seek time and rotational delay during simulation.
Question 6.
Explain how varying the bit density across tracks affects the overall storage efficiency of a hard disk. Provide a calculated example using arbitrary values.
Show hintHide hint
Calculate based on different storage needs for inner and outer tracks.
