Question: Assume a main memory with four page frames (frame A through frame D). Assume that the sequence of pages requested by a process is as

Assume a main memory with four page frames (frame A through frame D). Assume that the sequence of pages requested by a process is as shown below.

8, 5, 2, 9, 8, 9, 6, 1, 8, 5, 9

For each reference in the above sequence, identify whether it will cause a page fault (F) or will result in a page hit (H), when using the second chance page replacement algorithm. Use the table provided for your solutions use the Status column to indicate F or H and the Page Frame column to indicate the page frame into which the page has been loaded. Assume that all page frames are initially empty.

Note: the first few entries are already filled out for your reference.

Page Status Page Frame
8 F A
5 F B
2 F C
9 F D
8 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
9 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
6 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
1 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
8 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
5 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
9 [ Select ] ["F", "H"] [ Select ] ["A", "B", "C", "D"]
