企业内部通讯系统必须提供网络通讯功能、在通讯过程中禁止使用聊天表情、文件传送等功能，避免资料外泄，或因发送错误而导致上级资料的丢失以及其他损失。最重要的是必须适应任何操作系统，也就是实现跨平台技术，因为企业内部的工作需要，工作环境中使用了多个操作系统来完成不同的工作。另外，系统不需要使用服务器中转和记录通讯内容，可以独立完成通讯任务，排除职工对领导监视工作进度等逆反心理-Internal communication systems to provide network communication capabilities, in the communications process of the Prohibition of the Use chat expressions, such as file transfer capabilities, to avoid leakage of information, or send an error which led to the loss of higher-level information as well as other losses. The most important thing is to be adapted to any operating system, which is cross-platform technology, as businesses need to work within the working environment in the use of a number of different operating system to complete the work. In addition, the system does not require the use of transit and records of communications servers, you can independently accomplish the communication task, remove the leadership of trade unions to monitor the progress of the work of such an antagonistic mental

本次程序的题目为：进程管理――支持多个进程并发运行的简单的进程管理模拟系统，对本实验的分析要求是：⑴系统中的同步机构采用信号量上的P、V操作的机制；⑵控制机构包括阻塞和唤醒操作；⑶时间片中断处理程序处理模拟的时间片中断；⑷进程调度程序负责为各进程分配处理机；⑸根据用户的需求来创建n个进程(n为即满足用户需求,又不超出系统可容的最大进程数),各进程互斥地访问使用临界资源 S1、S2；⑹使用动态优先数(如：随阻塞次数的增加而减小优先数，以提高其优先权)；⑺进程结束后应能够撤消；⑻进程间能实现“发送”和“接收”两个消息缓冲通信操作；⑼系统在运行过程中随机打印出各进程的状态变换过程、系统的调度过程及公共变量的变化情况，在一个进程运行完毕，进入完成状态后，可以将该进程撤消，也可以动态的创建另一个新的进程。-the procedures on the topic of : process management-- to support multiple concurrent processes running a simple process management simulation system for the analysis of the experimental requirements are : 1 system of institutions using synchronous signals on the amount of P, V operation of the mechanism; 2 control agencies, including obstruction and awaken operation ; 3-time interrupt handling procedures-time simulation of interruption; 4 process scheduler is responsible for the allocation process processors; together according to the user"s needs to create process n (n that meet user needs, without exceeding the system can accommodate
