Sockets are one of the most popular means of network communication and they follow client-server architecture. I have created two programs, one to run on a client computer and
the other on the server computer. In my program I am showing how using a sockets client program can communicate to a server. The client program is run at the client-side while
the server program runs in the Internet. I am using a socket module which is provided by Python. When the client runs the echo-client.py program it is prompted to enter the
address to the server which could either be a domain name which I used for the testing or an IP address. Keep in mind that the server side program echo-server.py has to be running
in order for the connection to be established. Once the user enters the address to the server it’s prompted to enter a message for the server. Once he enters the message and presses
enter the message is send to the server. The server side program gets the message and displays it and also returns it back to the client. The final step for the server is to close itself
once that one cycle is complete. The client on the other side displays a message that the message has been received by the user and even shows it just to so the user is sure of it and
finally closes itself.
