Introduction
In this article we will look at how to program using sockets by implementing an echo
server along with a client that we will use to send and receive string messages. I will start
off by giving a quick introduction to TCP/IP fundamentals and then explain how sockets
fit into the picture. I am going to assume you already understand basic network concepts.
When you get done reading this article you should be armed with sufficient information
to be able to investigate other concepts in more detail on your own. Sample code can be
downloaded for this article from my website for anyone using VisualStudio 2008 or later.
I have also included all the source code in print at the end of the article for others.
Networks
Most network application can be divided into two pieces: a client and a server.
