Consider a system that has a 16KB address space and 64 byte pages and both page table entries and page directory entries are 4 bytes each. How many page directory entries are there?

Consider a system that has a 16KB address space and 64 byte pages and both page table entries and page directory entries are 4 bytes each. How many pages are needed to store the page table?

Consider a standard system 64-bit address space system and assume PTEs and PDEs are each 2 bytes. What is the smallest page size we can use to avoid a page table with more than two levels (i.e., to avoid having multiple page directories)?

What is a primary advantage of using large pages (e.g., 2MB) compared to standard pages (e.g., 4KB)?

What is a significant disadvantage of using large pages?
