In this article w ill 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.-In this article we will look at how to program using sockets by implementing an echo
