OS - memory management - paging
Consider a memory management system with two levels of paging in which a logical address is 32 bits which include 9bits for the first level table, 11 bits for the second level and the other for displacement.
What is the size of each page? What is the maximum number of pages per process?
Can you please help me with that? THANKS

The size of the page comes from the number of bits in the displacement, which is 32 - (9 + 11) or 12. The page size is 1 << 12 or 4096
The number of pages is 1 << (9 + 11), which is 1 << 20 or 1,048,576
