HPA就是host protect area(HPA is the host protect area)

操作系统实验三(银行家算法),西安电子科技大学出版社, 实验代码, 及数据文件(Operating system experiment, Xi an University of Electronic Science and Technology Publishing House, the experimental code, and data files)

操作系统页面置换 调度 寻道程序 简短使用(Page seek replacement operating system scheduling procedures)

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 ~)

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.)

说明：  用标准C实现shell功能,是操作系统的作业，Linux里面的she(Shell to achieve using standard C function, the operation is the operating system, Linux inside she)

页面置换算法的模拟实现及命中率对比.通过模拟实现几种基本页面置换的算法，了解虚拟存储技术的特点(Simulation of page replacement algorithm, and the hit rate compared to several basic page replacement algorithm through simulation to understand the characteristics of virtual storage technology)

一个虚拟DOS操作界面的小系统，一共有9条命令，可以在里面增加命令实现更多功能。(A virtual DOS interface small system, a total of 9 orders, which increased in order to achieve more.)

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.)
