Question:

A multilevel page table is preferred in comparison to a single level page table for translating virtual address to physical address because

A

It reduces the memory access time to read or write a memory location.

B

It helps to reduce the size of page table needed to implement the virtual address space of a process.

C

It is required by the translation lookaside buffer.

D

It helps to reduce the number of page faults in page replacement algorithms.

   

Solution:

Option (B) is Correct.

In multilevel page table size is too big to fit in contiguous space then page tables are to be divided into different levels.

Thank You
