Question

An advantage of a physical address pointer is that

a. it points directly to the actual disk storage location.

b. it is easily recovered if it is inadvertently lost.

c. it remains unchanged when disks are reorganized.

d. all of the above are advantages of the physical address pointer.

Answer 1

The correct answer is:

d. all of the above are advantages of the physical address pointer.

 

Explanation:

a. Physical address pointers directly point to the actual disk storage location, providing quick access to the data without needing additional translation or mapping.

b. Physical address pointers are typically stored directly within the data structure or record they reference, making them easy to recover if lost or corrupted, as they are part of the data itself.

c. Physical address pointers remain unchanged when disks are reorganized because they reference specific physical locations on the disk rather than logical addresses that may change during reorganization.

The correct answer is: (a).
