说明：  操作系统课社 1.理解内存页面调度的机理。 2.掌握几种理论页面置换算法的实现方法。 3.了解HASH表数据结构的使用。 4.通过课程设计比较各种调度算法的优劣。 5.熟悉页面置换算法及其实现，引入计算机系统性能评价方法的概念。页面置换算法是虚拟存储管理实现的关键，通过本次课程设计理解内存页面调度的机制，在模拟实现FIFO、LRU页面置换算法的基础上，比较两种置换算法的效率及优缺点，从而了解虚拟存储实现的过程。
(Operating System Division 1 clubs. To understand the mechanism of memory paging. 2. Have several theories page replacement algorithm method. 3. HASH table to understand the use of data structure. 4. Through the curriculum design to compare the merits of scheduling algorithm. 5. Familiar with the page replacement algorithm and its realization, the introduction of computer systems the concept of performance evaluation methods. Page replacement algorithm is the virtual storage management to achieve the key to the curriculum design through this understanding of memory paging mechanism to achieve in a simulated FIFO, LRU page replacement algorithm based on the comparison of the two replacement algorithm efficiency and the advantages and disadvantages to understand the virtual the realization of the process of storage.)
