网络编程普遍使用socket接口来实现网络间的进程通信，具体的TCP/IP细节被封装在内核之中，由内核完成；用户只需要使用内核提供的socket API来实现通信即可。Windows网络编程继承了Unix的socket接口，基本模式同Unix大同小异。但是由于两个系统的实现不同，在具体实现网络程序时仍存在一些差异。包括一些socket API的原型，以及并发服务器的编写方法等。-The widespread use of socket network programming interface to the process of communication between the network and the specific details of the TCP/IP is encapsulated in the kernel, done by the kernel　users only need to use the kernel socket API to communication can be. Windows network programming has inherited the Unix socket interface, much the same basic pattern with Unix. However, due to the realization of the two systems, there are still some differences in the concrete realization of the network program. Including some of the socket API prototype, as well as the compilation of concurrent server.
