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-related knowledge, procedures for the preparation of the network, Socket is connected applications and network bridge driver, Socket in your application to create, bind with the driver through the establishment of relations. Thereafter, the application data to the Socket, the Socket to the driver sent to the network. Computer from the network with the Socket Receive binding IP+ Port-related data, by the driver to the Socket, the application can be extracted from the Socket received data. Web applications is one such data through the socket send and receive. TCP and UDP and the preparation of the working principle of the process, how to link libraries in the proceedings document. A character interface chat program.
