A byte-oriented virtual memory system has the following characteristics: Virtual address: 32 bits Physical address: 34 bits Size of one page: 4,096 bytes The system uses a two-level page table. The top level of the page table is the Page Directory, where each entry in the Page Directory is 4 bytes wide. The second level of the page table consists of zero or more Page Maps, where each entry in a Page Map is 4 bytes wide. There is no internal fragmentation in the pages which hold the page table. How many page frames are present in the system? 2^22 frames (4,194,304 frames) 2^20 frames (1,048,576 frames) 2^11 frames (2,048 frames) 2^10 frames (1,024 frames) None of the above.
