Syn use to TCP/IP is the foundation of internet communication, and sockets provide a way for programs to send and receive data over the network. Socket programing is the key API for programming The following example shows how the Socket class can be used to send data to an HTTP server, printing the ASCII response to the standard output. Once the socket is connected, it can send and receive data from the server socket Socket addresses An application can communicate with a remote process by exchanging data with TCP/IP by knowing the combination of protocol type, IP address, and port number. Learn about the socket address, the socket API, and the different types of Internet Socket are generally employed in client server applications.
