24. A hard disk is divided into tracks which are further subdivided into:clusterssectorsvectorsheads

1. Break Down the Problem

The question asks about the components into which a hard disk is divided, specifically focusing on the subdivision of tracks.

2. Relevant Concepts

The correct terminology related to the structure of a hard disk includes:

• Tracks: Concentric circles on the surface of the disk.
• Sectors: The smallest unit of data storage within a track, typically holding 512 bytes.
• Clusters: Groups of sectors combined to form a logical storage unit used by the file system, which is often what is allocated to store a file.
• Heads: The read/write mechanisms that access the data on the disk surfaces.

3. Analysis and Detail

In a hard disk drive, data is organized in a hierarchical manner for efficient storage and retrieval:

• Tracks are the circular paths that data is organized into. Each surface of the disk has multiple tracks.
• Sectors are subdivisions of tracks. Each track is divided into several sectors. Typical sector sizes are 512 bytes or 4096 bytes.
• Clusters are composed of one or more sectors and are the smallest unit that the filesystem uses. Files are stored in clusters, not sectors.
• Heads are the components that read from and write to the disk. Each platters' side has a head that moves across the tracks.

4. Verify and Summarize

In summary, a hard disk is divided into tracks, which are further subdivided into sectors. Clusters are a group of sectors, while heads are the mechanisms that access these components.

Final Answer

A hard disk is divided into tracks, which are further subdivided into sectors. Clusters are groups of sectors used in the file system, and heads are the read/write devices on the hard disk.
