If many programs are kept in main memory, then there is almost always another program ready to run on the cpu when a page fault occurs. thus, cpu utilization is kept high. if, however, we allocate a large amount of physical memory to just a few of the programs, then each program produces a smaller number of page faults. thus, cpu utilization is kept high among the programs in memory.

what would the working set algorithm try to accomplish, and why? (hint: these two cases represent extremes that could lead to problematic behavior.)
