In a client-server architecture, there is one centralized server that provides service, and many clients request and receive service from the centralized server. Here are some methods you need to know:
socket.bind(address): This method is used to connect the address (IP address, port number) to the socket. The socket must be open before connecting to the address.socket.listen(q): This method starts the TCP listener. Theqargument defines the maximum number of lined-up connections.socket.accept(): The use of this method is to accept the connection from the client. Before using this method, thesocket.bind(address)andsocket.listen(q)methods must be used. Thesocket.accept()method returns two values:client_socketandaddress, where client_socket is a new socket object used to send and receive data over the connection, and address is the address of the client. You will see examples later.
