Consider the page sequence of Fig. 3-15(b). Suppose that the R bits for the pages B through A are 11011011, respectively. Which page will second chance remove?

Page loaded first Most recently loaded page 0 3 781214 15 18 A is treated like a newly loaded page 3 781 1415 18 20 Figure 3-15. Operation of second chance. (a) Pages sorted in FIFO order. (b) Page list if a page fault occurs at time 20 and A has its R bit set. The numbers above the pages are their load times
