2 cards from this section. Quick, good the night before a test.
What is constant angular velocity?
Think about what happens when a disk rotates.
Define seek time.
Consider the movement of a needle on a record player.
What maintains consistent retrieval time in disks?
Think about the definition of angular velocity.
True or False: Seek time is the same as rotational delay.
Consider the actions involved in both processes.
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.
Remember to convert RPM to radians per second for precise calculations.
How does using a zoned disk improve data read/write performance compared to a traditional uniform disk?
Consider the physical layout of data on the disk and how it affects retrieval efficiency.
