Ron Tovbin writes "Let’s start with the an overview of the basics. When you go to a web page, say, cnn.com , there is a lot going on behind the scenes to make that page show up in your browser. Remember, before anything can happen, a TCP/IP connection is established between your computer and the cnn.com webserver through port 80. Your browser will then start requesting “assets” to build the page. Some of these assets include HTML, CSS, Javascript and Image files, etc. They allow the browser to render the web page visible to you. "
