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.)

加深进程概念的理解；掌握选择进程调度算法的准则；掌握进程调度算法。 (Deepen the process of understanding of the concept master scheduling criteria selection process algorithm master process scheduling algorithm.)

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!)

哲学家进餐的问题，用程序模拟实现，解释死锁的产生、解除以及预防(dining philosophers problem, simulation procedures, explained Deadlock in lifting and prevention)

作业调度程序，模拟操作系统的作业调度过程，协调和控制各个作业对cpu的使用控制(Job scheduling program to simulate the process of the operating system job scheduling, coordinating and controlling the use of control operations on cpu)

操作系统实验-死锁避免算法，word文档，详细，全，可执行，自己写的，希望快点能在贵网站下载。。。(Operating System Experiment- Deadlock avoidance algorithm, word documents, detailed, full, enforceable, wrote it myself, hope quickly in your website. . .)

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)

模拟段式存储管理的分配与回收，能够输入给定的内存大小，进程的个数，每个进程的段数及段大小；当某进程提出申请空间的大小后，显示能否满足申请，以及为该进程分配资源后有关内存空间使用的情况。 (Analog-stage distribution of storage management and recovery, be able to enter a given memory size, number of processes, each process segment number and segment size when a space the size of the application process, the show can meet the application, as well as the The process, after the allocation of resources relating to the use of memory space.)

这是我做的操作系统里面的银行家算法的源程序，发上来供大家参考。(caozuoxitongyinhangjiasuanfa)

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)
