What defines a cylinder on a hard drive?

• A. It is a type of file system format
• B. A stack of tracks aligned vertically
• C. The outer edge of the disk platter
• D. The total number of partitions available

Answer: (B)

A cylinder on a hard drive is defined as a stack of tracks aligned vertically across multiple platters. Each platter in a hard drive has concentric circles known as tracks, and these tracks are aligned so that they form a continuous vertical column or cylinder when you look at them across the platters. The cylinder concept is significant because it allows the read/write head to access multiple tracks simultaneously, making data retrieval and storage processes more efficient. Understanding this definition is essential for grasping how data is organized on a hard drive and the physical layout of magnetic storage media. The other options pertain to different concepts related to data storage, such as file systems, platter edges, and partitions, but they do not describe the structural organization of tracks and how they relate to forming a cylinder on a hard drive.
