面向连接的服务器流程中，必须设置服务器套接字为监听状态；而客户机则是主动连接。无连接客户机和服务器。无连接客户机和服务器在调用的函数方面没有区别，区别在于服务器一般先启动recvfrom等待客户机的数据。客户机和服务器的通信过程为客户向服务器发送数据，服务器收到数据后给予应答，通信结束。-connection-oriented server process, you must set up to monitor server socket state; While the client is active connector. Without connecting client and server. Without connecting client and server in a function called no distinction, the general difference is the server for first launching recvfrom client data. Client and server communication process for clients to send data to the server, the server data received responses and communication end.

客户机/服务器模型是为了解决通信中的聚合问题。如果不采用客户机/服务器模型很难实现正常的通信，只有在一方作为服务器采用被动方式，始终等待对方与其通信；另一方作为客户机采用主动通信的方式，主动发起通信过程，才能最终完成通信。-client/server model is to solve the communication problems polymerization. If we do not use the client/server model is very difficult to achieve normal communications, as one of only a passive server, which has been waiting for communication with the other side; The other client as an active communication, initiate the communication process can be finalized communications.
