银行家算法模拟，适用于计算机操作系统课程设计的银行家算法的实现。(Bankers algorithm simulation for realization of computer courses on operating system design bankers algorithm.)

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)

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 ~)

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.)

说明：  ucos2 vc++移植代码 通过VC++编译，每2S显示一次任务(ucos2 vc++ code migration)

经典问题魔兽世界（wumpus world）的程序，还比较简单，只能在dos下文字表示，没有图示(classic World of Warcraft (chat world) procedures, but also relatively simple, only under the dos text, there is no icon)

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.)

进程和线程技术 Linux和windows进程创建 进程和线程通信 文档+实例分析(process and thread Technology Text and examples)

说明：  Unix 成组链接法 模拟UNIX系统的空闲块成组链接法，实现磁盘存储空间的管理(Unix Group Links UNIX System Simulation of spare pieces Group link, disk storage space to achieve the management)
