存储管理请求分页置换算法 用到的先进先出FIFO、最近最久未使用LRU、最佳OPT置换算法。熟悉文件的基本操作（读、写）。-Replacement algorithm for storage management, demand paging used FIFO FIFO, the most recent long-lost the use of LRU, the best OPT replacement algorithm. Are familiar with the basic file operations (read, write).

操作系统课件，ppt格式，总共七章，个人觉得还不错-operation system ppt

线程同步机制。 互斥器的功能和临界区域很相似。区别是：Mutex所花费的时间比Critical Section多的多，但是Mutex是核心对象(Event、Semaphore也是)，可以跨进程使用，而且等待一个被锁住的Mutex可以设定TIMEOUT，不会像Critical Section那样无法得知临界区域的情况，而一直死等。-Thread synchronization mechanism. Mutex" s function and the critical region is very similar. The difference is: Mutex spent more time than the multi-Critical Section, but the Mutex is the core object (Event, Semaphore is), you can cross-process use, and has been locked waiting for a Mutex can be set to TIMEOUT, not as Critical Section did not know the critical situation in the region, for so long and so die.

这是一个操作系统（计算机系课程）的课程设计。它的功能是模拟文件管理,包括建立用户,建立文件并对文件设置属性.还包括对文件的添加,修改,删除等操作-This is an operating system (computer science courses) are designed. Its function is simulated document management, including the establishment of users, document also set up document attributes. The document also includes the addition, modification, deletion, etc

采用首次适应法、最佳适应法或最差适应法，编写一内存分配和回收模拟程序。 动态地随机产生新的“内存分配”或“内存回收”请求，再按照你选定的分配算法修改这个数组。由于这个实验的重点在于内存分配，所以不考虑与某内存区相关的进程情况。-used first to adapt, adapt best or the worst adaptation law, the preparation of a memory allocation and recovery simulation program. Dynamic random to create a new "memory allocation" or "memory recovery" request, then you have chosen in accordance with the allocation algorithm to change the array. As the focus of this experiment is memory allocation, it is not considered relevant to a certain memory area of the process.
