Question 1 : A multilevel page table is preferred in comparison to a single level page table for translating virtual address to physical address because :
1. it reduces the memory access time to read or write a memory location
2. it helps to reduce the size of page table needed to implement the virtual address space of a process
3. it is required by the translation lookaside buffer
4. it helps to reduce the number of page faults in page replacement algorithms
