通过在第1部分实验基础上，完成实现进程的分页式内存分配和地址转换过程，并进一步完成请求分页式存储分配和地址转换过程。掌握分页式存储管理和请求分页存储管理、并掌握页面置换先进先出（FIFO）、最近最久未使用（LRU）等算法-Through to complete paging memory allocation and address of the realization process of the conversion process, based on the first part of the experiment, and further to complete the requested the paging storage allocation and address translation process. Master paging storage management and the demand paging storage management, and mastery of the first-in, first-out (FIFO) page replacement, most-recently-used (LRU) algorithm
