网络的相关知识，网络程序的编写，Socket是连接应用程序与网络驱动程序的桥梁，Socket在应用程序中创建，通过bind与驱动程序建立关系。此后，应用程序送给Socket的数据，由Socket交给驱动程序向网络上发送出去。计算机从网络上收到与该Socket绑定的IP+Port相关的数据后，由驱动程序交给Socket，应用程序便可从该Socket中提取接收到的数据。网络应用程序就是这样通过socket进行数据的发送与接收的。TCP与UDP的工作原理与编写过程，如何在程序中链接库文件。一个字符界面的聊天程序。-network of the knowledge, network program, Socket is a link between the application and network drivers for the bridge, Socket in the application process to create, Driving through bind with the procedures established relations. Since then, Socket applications presented data from the socket to the network driver to send out. Computer network received from the socket and bundled IP Port-related data, from driver to Socket, applications from the Socket can extract the data receiver. Web applications is through this socket for data transmission and reception. TCP and UDP Principle and the work of the preparation process, and how to process link libraries. A character based chat program.

聊天室的设计，是一个简单的例子，适合新手学习-chat room was designed as a simple example for newcomers to learn

简单的p2p应用 可以实现远程消息传输 并且以后的任务可以实现p2p文件传输-simple peer-to-peer applications can be remote messaging and the future task can achieve peer-to-peer file transfer

首先，客户端的日志服务器，网络地址转换分布为本届会议的一个端口60000 ，那么伺服器收到了用户端的地址是202.187.45.3:60000 ，这是外部的客户网络地址。同样，客户乙登入伺服器， B至吨的NAT-First of all, Client A log server, NAT A distribution for the Session of a port 60000, then the Server S received the address of Client A is 202.187.45.3:60000, which is outside of the Client A network address. Likewise, Client B Login Server S, NAT B to the distribution of the Session of the port is 40000, then the Server S received B s address is 187.34.1.56:40000. At this time, Client A and Client B and Server S can be a communication. If Client A at this time would like to direct
