Problem
A virtual memory page can be loaded into any page-frame of the physical memory. A table, called a page table, is used to ?nd the page-frame of the physical memory where a virtual-memory page is located, if the page is present in the physical memory. Assumed that a computer has 128-word physical memory and 1024-word virtual memory.
1. What is the minimum size of a page table? Explain.
2. For the minimum size page table how many words are necessary? Assume that length of a word is no less than the number of bits of a virtual memory address.
3. Draw the format of the minimum size page table.
4. What is the maximum size of a page table? Explain.
5. For the maximum size page table hovxr many words are necessary? Assume that length of a word is no less than the number of bits of a virtual memory address.
