通过内存查询结果确定分页存储管理的原理和使用方法，并能通过内存回收，完成内存的有效使用，为了能支持虚拟存储器功能而增加了请求调页功能和页面置换功能，而请求分页是目前最常用的一种实验虚拟存储器的方式。实验中运用页表机制确定占用内存情况。-Memory paging through query results to determine the use of storage management principles and methods, and through memory recovery, complete the effective use of memory, in order to support the virtual memory function and increased demand paging and page replacement feature functions, and demand paging is The most commonly used way of an experimental virtual memory. Experiments in the use of memory for page table mechanism to determine the situation.
