Introduction to Operating Systems. . Virtual Memory Sample Questions. 0. Page Table. Q: Consider a system with 32-bit virtual address. The virtual memory is implemented by paging, and the page size is 4KB. A user process generates the virtual address 0x11123456. What is the page table index for this virtual address? . Tore Larsen.
