    Do I have a web server running?


having a web server turned on doesn't necessarily mean you are serving pages on the world wide web.  its what allows you to load your own static files (.html, .js etc.) in a browser via http://.
if you're not sure whether or not you have a web server running, no problem!  its easy to confirm.
what happens when you visit http://localhost/?
