Question: Operating Systems: 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

Operating Systems:

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.

Operating Systems: The following page table is for a system with 16-bit

A.) Convert the following virtual addresses (in hexadecimal) to the equivalent physical addresses. Provide answers in hexadecimal. Also set the reference bit for the appropriate entry in the page table.

0xF12C

0x5A9D

0xB9D9

0x6001

0x9CA1

B.) Using the above addresses as a guide, provide an example of a logical address (in hexadecimal) that results in a page fault.

C.)From what set of page frames will the LRU page-replacement algorithm choose in resolving a page fault?

Page Page Frame Reference Bit 1 0 22 14 0 3 10 0 5 13 0 6 8 0 7 15 0 9 0 0 5 0 10 11 4 0 0 12 0 13 3 0 14 15
