D. The hard disk data addressing happens on the physical blocks of data on the hard drives, but the method of allotting only happens on the (Logical Block Address) data addressing type.
There are two types of hard disk data addressing:
1. CHS (Cylinder-Head-Sector)
2. LBA (Logical Block Address)
The answer is D. Logical block. Hard disk data addressing is a method of allotting addresses to each logical block of data on a hard disk. A logical block is a unit of data that is independent of the physical characteristics of the storage device, such as the number of sectors, tracks, or cylinders.
Hard disk data addressing is a method of assigning logical block addresses to each block of data on a hard disk. A logical block is a fixed-size unit of data that is accessed by the operating system and represents a segment of a file or a portion of free space on the hard disk.
The physical organization of a hard disk is typically divided into sectors, tracks, and cylinders, which are used to locate data on the disk. However, logical block addressing is used by the operating system to manage and access data on the disk, rather than using physical addresses.
Option A, physical block, refers to a physical unit of data storage on the hard disk.
Option B, operating system block, is not a commonly used term in the context of hard disk data addressing.
Option C, hard disk block, is also not a commonly used term in the context of hard disk data addressing.
