Question 1.
What does constant angular velocity mean in terms of disk operation?
Show hintHide hint
Think about how speed affects timing.
Question 2.
Explain what seek time refers to.
Show hintHide hint
Consider the action of moving.
3Question 3.
What is constant angular velocity?
- The disk rotates at variable speed
- The disk rotates at a constant speed
- The disk does not rotate
Show hintHide hint
Focus on the meaning of 'constant'.
4Question 4.
True or False: Seek time is the time taken to transfer data once the read/write head is in position.
- True
- False
Show hintHide hint
Consider the steps in accessing data.
Question 5.
If a hard disk rotates at 7200 RPM, calculate the time taken for one full rotation. How would this time affect data access?
Show hintHide hint
Think of how RPM translates to time.
Question 6.
Consider a disk that uses zone bit recording with three zones. If the inner zone holds 100 bits and increases by 50 bits per zone outward, what would be the bit capacity of the outer zone?
