Socket programming is a way of connecting two nodes on a network to communicate with each other. One socket(node) listens on a particular port at an IP, while other socket reaches out to the other to form a connection. Server forms the listener socket while client reaches out to the server. Server Socket Methods 1 s.bind() This method binds address (host name, port number pair) to socket. 2 s.listen() This method sets up and start TCP listener. 3 s.accept() This passively accept TCP client connection, waiting until connection arrives . Client Socket Methods s.connect() This method actively initiates TCP server connection. General Socket Methods 1 s.recv() This method receives TCP message 2 s.send() This method transmits TCP message 3 s.recvfrom() This method receives UDP message 4 s.sendto() This
