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)

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.)

制冷专业软件，非常实用，可计算制冷系统，制冷剂的物性(Refrigeration professional software is very useful, computable refrigeration system, refrigerant properties)

可以控制标签的各种状态，包括大小，字体等等，只要你能想到(Can control a variety of status labels, including size, fonts, etc., as long as you can think of)

1．虚拟存储器的引入 局部性原理：程序在执行时在一较短时间内仅限于某个部分；相应的，它所访问的存储空间也局限于某个区域，它主要表现在以下两个方面：时间局限性和空间局限性。 2．虚拟存储器的定义 虚拟存储器是只具有请求调入功能和置换功能，能从逻辑上对内存容量进行扩充的一种存储器系统 (1. The introduction of virtual memory locality principle: program execution in a relatively short period of time limited to a particular part of it Accordingly, it has access to the storage space is also limited to a particular region, it is mainly manifested in the following two aspects: the time limitations and space limitations. 2. The definition of virtual memory Virtual memory is just a request for redeployment of functions and displacement functions, from the logical to expand the memory capacity of a memory system)

操作系统 实验二 进程同步与互斥 实现的基本的进程的同步、互斥，并用银行家算法实现与死锁预防(Second, the process of experimental operating system synchronization and mutex realize the basic process synchronization, mutual exclusion, and bankers with the deadlock prevention algorithm)

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)

广东工业大学计算机学院操作系统4源代码 (Guangdong University of Computer Science 4 source code operating system)

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.)

模拟操作系统进程调度的算法采用时间片轮转法和优先权法(operating system simulation process scheduling algorithm-time Web-law and law priority)
