(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

This question was posed to me in unit test.

My query is from Memory Management in chapter Memory Management of Operating System

Answer 1
