What is network programming? Baidu Encyclopedia: network programming, in a big way, is the function of sending and receiving information, and the intermediate transmission is the physical line. The main work of network programming is to assemble the information package through the specified protocol at the sending end, and analyze the packa ...

UDP network programming one-way and two-way exception handling of Socket socket Socket It is used to describe the IP address and port. It is the handle of the communication chain. The application sends or responds to the network request through the SocketIt is the basic operation unit of network communication supporting TCP/IP protocol,It is ...

0. General In a technical sense, because TCP needs to establish a connection, UDP can "throw vegetables" directly Therefore, only TCP protocol has Server server and Client client. For UDP protocol, there is no Server and Client UDP protocol features: UDP is a connectionless and unreliable transmission protocolEncapsulate ...
