Hard disk data addressing is a method of allotting addresses to each ____ of data on a hard disk.

Hard disk data addressing is a method of allotting addresses to each ____ of data on a hard disk.

• A. Logical block
• B. Physical block
• C. Operating system block
• D. Hard disk block

Answer: (B)

Hard disk data addressing focuses on locating data by its position on the physical medium. The drive stores data in fixed-size physical blocks, each with a physical address defined by the disk’s geometry or by the drive’s internal linear addressing. The operating system and file system work with logical blocks as an abstraction, mapping them to the underlying physical blocks. So the actual location of data on the disk is described in terms of physical blocks. Logical blocks describe the OS-level view, not the hardware location.
