A network socket is an internal endpoint for sending or receiving data within a node on a computer network.Concretely, it is a representation of this endpoint in networking software (protocol stack), such as an entry in a table (listing communication protocol, destination, status, etc.), and is a form of system resource.The term socket is analogous to physical female connectors, communication.

The socketserver module simplifies the task of writing network servers. There are four basic concrete server classes: class socketserver.TCPServer (server_address, RequestHandlerClass, bind_and_activate=True) ¶. This uses the Internet TCP protocol, which provides for continuous streams of data between the client and server.
