LBA (Logical Block Address) addresses data by allotting a ___________to each sector of the hard disk.

LBA (Logical Block Address) addresses data by allotting a ___________to each sector of the hard disk.

• A. Sequential number
• B. Sector number
• C. Index number
• D. Operating system number

Answer: (A)

Logical Block Addressing assigns a simple, sequential numeric address to each sector, turning the disk into a linear sequence of fixed-size blocks. This abstraction lets software locate data without needing to model the drive’s physical geometry (like cylinders and heads). Each sector gets a unique number, usually starting from zero and increasing by one for each subsequent sector, which is why the concept is described as using a sequential number. This makes imaging and forensic analysis consistent across tools because every block has a stable, simple address.
