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

The correct answer is A. Sequential number. Logical Block Addressing (LBA) is a modern method of addressing the location of data blocks stored on storage devices. Unlike the older CHS (Cylinder-Head-Sector) method that used physical geometry, LBA assigns a unique sequential number (starting from 0) to each sector on the…

Explanation

Logical Block Addressing (LBA) is a modern method of addressing the location of data blocks stored on storage devices. Unlike the older CHS (Cylinder-Head-Sector) method that used physical geometry, LBA assigns a unique sequential number (starting from 0) to each sector on the disk, making it easier for the operating system and storage controllers to locate data. This linear addressing scheme simplifies disk management and supports larger drive capacities beyond CHS limitations.
