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!)

银行家算法模拟程序的实现 用可视（图形）化界面完成银行家算法的模拟程序。 模拟程序能够实现对不同数目进程，不同数目资源种类，不同当前状态的测试，通过银行家算法判断任意次数的资源请求是否会得意满足，并对提出资源请求的进程作出正确处理。 模拟程序还需要能够正确回收资源，并在回收资源后判断是否需要唤醒阻塞进程，如需要则将先前因申请资源失败而被阻塞的进程唤醒，并提供资源分配(Bankers algorithm simulation program realization )

计科操作系统课程“读者写者”问题的经典解决。(Branch of the operating system programs, " wrote the reader" as a problem to solve classic.)

简单的文件系统试验源代码，可用于操作系统的大型实验~~(Simple test source code of the file system, the operating system can be used for large-scale experiments to ~)

模拟操作系统进程调度：运行状态，就绪状态和完成状态。包含有first() prisch() insert1(q) creat(gg) prish() roundsch() 函数的引用。(Simulate the operating system process scheduling: running, ready states, and completion status. Contains the first () prisch () insert1 (q) creat (gg) prish () roundsch () function reference.)

说明：  这是操作系统中调度算法中时间片轮转算法完成后的实践报告(This is the operating system scheduling algorithm in the time slice cycle after the completion of practice report)

1）设计一程序，由一个进程创建三个子进程，三个子进程一个是生产者进程，两个是消费者进程。 2）父子进程都使用父进程创建的共享存储区进行通信，由生产者进程将一个数组中的十个数值发送到由5个缓冲区组成的共享内存中。? 3）两个消费者进程轮流接收并输出这十个数值，同时将两个消费者进程读出的数值进行累加求各和。 4）考虑生产者进程生产的速度和消费者进程速度。(1) a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process. 2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L 3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes. 4) take into account the production speed of the producer process and the speed of the consumer process.)

操作系统文件管理实验：利用交互式命令实现树型目录结构和文件管理,同时利用位示图表示外存的分配情况，新建文件时分配必要的空间，模拟文件分配表记录文件在外存上的存储方式。了解系统对文件的操作。 在文件中保存目录内容，创建文件或子目录可以用命令行命令：MD、CD、RD、MK（创建文件）、DEL（删除文件）和DIR(Operating system file management experiment: the use of interactive command tree directory structure and file management, while taking advantage of the bit map indicates the distribution of the external memory, and allocate the necessary space when a new file is created, the simulation file allocation table log file is stored in the external memory way. Understanding of the system operation on the file. Save the contents of a directory in the file, create a file or subdirectory can use the command-line command: MD, CD, RD, MK (create a file), DEL (delete files) and DIR)
