Question

When there is a large logical address space, the best way of paging would be :

a) Not to page
b) A two level paging algorithm
c) To page the page table itself
d) All of these

Answer 1

The best way of paging when there is a large logical address space is a two level paging algorithm. This approach efficiently manages the page table and reduces overhead.

Step-by-step explanation:

The best way of paging when there is a large logical address space is a two level paging algorithm. This approach is used to efficiently manage the page table and reduce the overhead of accessing the page table for each memory reference.

In a two-level paging algorithm, the logical address space is divided into multiple levels of page tables. The first-level page table contains pointers to second-level page tables, which in turn point to physical memory frames. This hierarchical structure allows for better organization and faster access to the page table entries.

Paging the page table itself may also be done in certain cases, but it is not the best approach in general and can introduce additional complexity and overhead.
