The __________ is used as an index into the page table.

b) Page number
c) Page offset
d) Frame offset

Answer 1

The page number is used as an index into the page table for address translation from virtual to physical in an operating system's memory management system.

Step-by-step explanation:

The page number is used as an index into the page table. When a virtual address is being translated to a physical address by the operating system, it can be split into two parts: the page number and the page offset. The page number acts as a key to the page table where the corresponding frame number is stored. This frame number, combined with the page offset, gives the physical address in memory where the required data is stored.
