A computer has four page frames. The time of loading, time of last access, and the $R$ and $M$ bits for each page are as shown below (the times are in clock ticks):
Ans: (a) Page 1 because R M = 0 0
(b) Page 3 because it is loaded at 110 (First In)
(c) Page 1 because is referenced at 265 (Least Recently)
(d) Page 1 because it is loaded at 120 and the reference bit is 0.
