一个操作系统的源代码，实现了进程管理等功能(operating system source code)

页面置换先进先出算法，请大家试试，本人鉴定没问题(FIFO page replacement algorithm, please try, I did not identify the problem)

说明：  ucos2 vc++移植代码 通过VC++编译，每2S显示一次任务(ucos2 vc++ code migration)

对于iOS调标签类别，精选ios编程学习，很好的参考资料。(For the iOS label category, select the IOS programming learning, a good reference.)

功能完整的瀑布墙视图效果，精选ios编程学习源码，很好的参考资料。(View full-featured waterfall wall effect, selection ios programming learning source, a good reference.)

说明：  操作系统银行家算法，C#编写，比较漂亮，有用！(OS Banker' s algorithm, C# prepared, more beautiful, works!)

说明：  模拟操作系统进程调度(先来先服务，优先级优先，相应比优先，最短作业优先），资源抢夺，内存分配功能（动态分区，静态分区）（最坏适应法，最佳适应法，FIFO）(Simulation operating system process scheduling (first come first serve, priority first, corresponding ratio first, shortest job first), resource grabbing, memory allocation function (dynamic partition, static partition) (worst adaptation, best adaptation, FIFO))

FIFO和LRU页面置换算法，使用c++写的，有功能号，可以选择功能，进行相应的操作！(FIFO and LRU page replacement algorithm, using c++ written in the functional number, you can choose functions to carry out the appropriate action!)

内存静态分配： 程序还有一些错误，益出处理不知道怎么加入。此程序开始不是我写的的，我在别人的基础上理解并改动了一些。实验课已经结束了，没时间在做了，以后有机会再改。(static memory allocation : there are some procedural error, derived from processing do not know how to join. This is not the beginning of the proceedings I write, I others on the basis of understanding and change some of it. Experiments over, and no time to do in the future will have the opportunity to change.)

这个程序是模拟采用二级目录结构的磁盘文件系统中的文件操作，它可以实现对文件的一些基本管理，如：读、写、删除文件等。通过这个程序可掌握文件子系统的原理，加深对二级目录结构的文件系统中用户管理、文件管理、目录管理的理解，并用程序实现对文件子系统的模拟。(the procedure is simulated using two disk directory structure of the file system file manipulation, it can be achieved on some basic document management, such as : read, write, delete files. Through this procedure can grasp the principle document subsystems to enhance the structure of the two file system user management, document management, directory management, understanding, and the procedures to achieve the right documents subsystem simulation.)
