某虚拟存储系统采用最近最少使用(LRU)页面淘汰算法，假定系统为每个作业分配4个页面的主存空间，其中一个页面用来存放程序。现有某作业的程序如下：
Var A: Array[1..100, 1..100] OF integer;
i, j: integer;
FOR i:=1 to 100 DO
FOR j:=1 to 100 DO
A[i,j]:=0;
设每个页面可存放200个整数变量，变量i、j存放在程序页中。初始时，程序及i、j均已在内存，其余3页为空。若矩阵A按行序存放，那么当程序执行完后共产生 (3) 次缺页中断；若矩阵A按列序存放，那么当程序执行完后共产生 (4) 次缺页中断。
| If books had never been discovered, man
would have found some other way of recording his communication. But then, for
our consideration, we should include as books everything that is a written
record. This would include tablets, papyrus and anything else—including computer
diskettes. In the case of music, it would be impossible to think that man can
live without it. Looking at primitive cultures, it appears that music is
actually a part of the human psyche. When two things are knocked together, music
is produced. So for the sake of our discussion, it is intended to restrict the
meaning of music to the popularly accepted concept. Music is the pleasing
combination of sounds that we like to listen to. Though it is difficult to, we can pretend that these things never existed. In this case we would not miss them today.
