Disk storage systems Question#1 (True/False) A track is divided into multiple units called sectors.

Disk storage systems Question #2 (True/False) A sector consists of multiple tracks.

Disk storage systems Question #3 A ___________ consists of all tracks accessible from a single position of the read/write heads of a hard drive.

Disk storage systems Question #4 (True/False) Physical sectors are always 512 bytes because the sectors are marked on the disk by the manufacturer.

Disk storage systems Question #6 Why are files initially stored in adjacent cylinders?

Disk storage systems Question #7 When a file’s storage becomes fragmented, what does this mean in terms of cylinders and seek operations performed by the drive?

Disk storage systems Question #8 Another name for a drive partition is a drive ________.

Disk storage systems Question #9 What does a drive’s average seek time measure?

Disk storage systems Question #10 What is a low-level format?

Disk storage systems Question #11 How many primary partitions can there be on a hard drive?

Disk storage systems Question #12 How many extended partitions can there be on a hard drive?
