- Part 1. Consider a virtual memory system with 24-bit virtual address space. If the page size of 8 KB is used when we split into a logical address, how many bits will be used for the page number, and how many bits will be used for the offset? Using the 24-bit virtual address space, if we use a page size of 4 KB when we split into a logical address, how many bits will be used for the page number, and how many for the offset?
Part 2. What do you think is an advantage and a disadvantage of a smaller page size in a virtual memory system? What do you think is an advantage and a disadvantage of a larger page size in a virtual memory system?
