操作系统作业源代码，方便学习操作系统课程的同学使用 (this is the codes for students who learn computer system.)

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)

说明：  请求页式虚存管理是常用的虚拟存储管理方案之一。通过请求页式虚存管理中对页面置换算法的模拟，有助于理解虚拟存储技术的特点，并加深对请求页式虚存管理的页面调度算法的理解。(Page requests virtual memory management is commonly used in the virtual storage management, one of the options. Page through the request of the management of virtual memory page replacement algorithm for simulation, helping to understand the characteristics of virtual storage technology, and better understanding of the request for virtual memory management Page page scheduling algorithm understanding.)

磁盘文件系统：建立基于磁盘存储设备的UNIX文件系统，在windows系统下模拟UNIX文件管理系统，可用命令行进行基本的文件操作。(Disk file system: the UNIX file system based disk storage devices in the windows system simulation UNIX file management system, basic file operations available command line.)

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.)

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 )

MFC实现的，界面有好，实现了进程调度的算法 能够模拟操作系统的进程调度 适合初学者(MFC implementation, the interface is good, a process scheduling algorithm to achieve To simulate the operating system process scheduling for beginners)

这是一个进程调度问题~~~~还是有很多的问题哦(This is a process of scheduling problem ~ ~ ~ ~ still has many problems Oh)

驱动调度+操作系统+模拟电梯调动的算法程序，使用C++编写。(Driven scheduling algorithm procedures, the+ operating system+ simulated lift mobilize written using the C++.)
