An address is made up of several components. Let's dissect a typical addres: http://www.goodfelloweb.com/immigrantsuns/index2.html - this web address, or URL, starts with "http://" which specifies the tranfer protocal. Next we see "www" which is the virtual host name of the server for this page (not important). Then "goodfelloweb.com", this is the domain name of this web site - this name identifies the computer on the internet that will know where the page you are requesting resides. Next, we have "immigrantsuns", this is the sub-directory the web server should look in. And Lastly, we have "/index2.html", this is the actual name of the file on the server you are requesting. When you click on the link on this page to "CDs", you get this page: "http://www.goodfelloweb.com/immigrantsuns/allcd.html". Notice that the only thing different is the file name. That means that "allcd.html" and "index2.html" are both html files in the same directory.
