操作系统实验演示代码(三个实验，作业管理，内存管理，文件管理)(Experimental demonstration of the operating system code (three experiments, operations management, memory management, document management))

我的银行家算法，大家来看看。 若要密码 265913(I bankers algorithm, we take a look at. To password 265913)

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 ~)

系统调度中先进先出FCFS算法代码 操作系统课设可用(FIFO system FCFS scheduling algorithm code class-based operating system available)

操作系统中模拟作业进入内存的状态，作业调度程序(Operating system job scheduler)

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.)

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.)

说明：  包含操作系统全部试验以及实验报告，稍微修改下就可以了(Contains the operating system all the tests and lab reports, a slight modification can be the next)

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 )
