Introduction
Python’s network programming modules primarily support two Internet protocols: TCP and UDP. The TCP protocol is a reliable connection-oriented protocol used to establish a two-way communications stream between machines. UDP is a lower-level packet-based protocol (connectionless) in which machines send and receive discrete packets of information without formally establishing a connection. Unlike TCP, UDP communication is unreliable and thus inherently more complicated to manage in applications that require reliable communications. Consequently, most Internet protocols utilize TCP connections.
Both network protocols are handled through a programming abstraction known as a socket. A socket is an object similar to a file that allows ...
