7. A volume set is two or more partitions that have been combined into a single logical drive.

8. Disk mirroring (including duplexing); disk striping with a parity stripe; disk striping with a parity drive

9. Disk mirroring uses a single controller and two drives to mirror data. Disk duplexing uses two controllers and two drives to mirror data.

10. False. You can regenerate a stripe set only if a single drive fails. If two or more drives fail, you must restore data from the most recent backup.

11. True

12. Online storage is available without any user intervention. Offline storage requires the user to access the data from media that is not immediately accessible.

13. 640MB

14. SuperDisk and HiFD are backward compatible with 1.44MB floppy disks.

15. A DVD holds 13 times the amount of data as a CD, enabling DVDs to store several high-quality, full-length digital movies. Also, DVD players are backward compatible with CDs.

16. True
