A computer with a 64-bit address uses a three-level page table. Virtual addresses are split into a 16-bit top-level page table field, a 16-bit second-level page table field, a 16-bit third-level page table field, and an offset. Physical memory is 16 GB. Page table entry is 4 bytes. How large are the pages? How many pages are there in the address space? What is the number of physical frames? How many entries can the top-level page table accommodate? What is the size in bytes of each of the third-level page tables
