Challenge Problems
Push your limits with challenges.
Question 1
A disk rotates at 7200 RPM. Calculate the average access time if the average seek time is 4ms and average rotational delay is 2.5ms.
💡 Hint: Remember to convert RPM to radians per second for precise calculations.
Question 2
How does using a zoned disk improve data read/write performance compared to a traditional uniform disk?
💡 Hint: Consider the physical layout of data on the disk and how it affects retrieval efficiency.
