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.
