Question 7: What is the purpose of zoned-bit recording in a disk?
A) To increase data storage capacity
B) To organize tracks into zones
C) To reduce seek time
D) To improve disk performance
Explanation: Zoned-bit recording organizes tracks into zones.
Question 8: What is seek time in a mass storage device?
A) Time required to read data
B) Time required to write data
C) Time required to move heads between tracks
D) Time required to spin up the disk
Explanation: Seek time is the time required to move heads between tracks.

A) Time required for the disk to start spinning
B) Time required for the disk to complete one rotation
C) Time required for the desired data to rotate around to the read/write head
D) Time required for the read/write head to reach the desired track
Explanation: Rotation delay is the time required for the desired data to rotate around to the read/write head.
Question 10: What is access time in a mass storage device?
A) Time required to access the disk
B) Time required to access a sector
C) Sum of seek time and rotation delay
D) Sum of seek time, rotation delay, and transfer time
Explanation: Access time is the sum of seek time and rotation delay.
Question 11: What is transfer rate in a mass storage device?
A) Rate at which data can be transferred to or from the disk
B) Rate at which the disk spins
C) Rate at which the read/write head moves
D) Rate at which the disk accesses data
Explanation: Transfer rate is the rate at which data can be transferred to or from the disk.
Question 12: Which component of a mass storage device is responsible for holding data?
A) Sectors
