URGENT In multilevel paging, the page table having a size greater than the frame size can be divided into several parts in order to fit each page table into a frame. Suppose that we have a computer system with a 31-bit multilevel logical address and 1 KiloByte page size. Assume that each entry in a page table is 2 Byte. What is the minimum number of levels to satisfy the constraint that each page table can fit in a frame? (that is, the size of each page table should not be greater than a frame)
