The following page table is for a system with 16-bit virtual and physical addresses and with 4,096-byte pages. The reference bit is set to 1 when the page has been referenced. Periodically, a thread zeroes out all values of the reference bit. A dash for a page frame indicates the page is not in memory. The page-replacement algorithm is localized LRU, and all numbers are provided in decimal. Page Page Frame 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 9 2 13 10 14 8 15 OSTI 1-3 0 AGO 5 Reference Bit 0 1 0 0 0 0 0 Virtual Address OxE13C 0x5A9D 0xF9D9 0x7011 OxACA2 0 0 0 1 0 0 0 1 0 A. Convert the following virtual addresses (in hexadecimal) to the equivalent physical addresses(hex). Physical Address B. Using the above addresses as a guide, provide an example of two logical address in different pages (in hexadecimal) that will result in a page fault. Answer: C. From what set of page frames will the LRU page-replacement algorithm will not choose in resolving a page fault? Answer:
