Creating a server-side application


Networking plays a major role in modern life. We need to understand how communication is established between two machines. When two machines communicate, one is usually a server and the other is a client. The client sends requests to the server and the server responds by serving the request made by the client. 

In this recipe, we will be creating a client-server application where a connection is established between client and server and each will be able to transfer text messages to the other.
