Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does rotating at a constant angular velocity imply for time management?
- More time needed to retrieve data from outer tracks.
- Same time for data retrieval
- regardless of track location.
- Variable time based on speed variations.
💡 Hint: Think about the implications of consistent speed.
Question 2
Is seek time defined as the time taken to bring the correct sector beneath the read-write head?
- True
- False
💡 Hint: Consider seeking and waiting as different processes.
