title: What is localhost:8000 as used in Codecademy (for AngularJS and Ruby on Rails tutorials)?
body: <p>I want to know what is this: <code>localhost:8000</code>, found in Codecademy tutorials for AngularJS and Ruby on Rails. I even installed Apache 2, but to work with it I need to dial: <code>http://localhost/</code>. While working on some html files, I often come across Firefox's Inspect Element where a section is to mention <code>localhost</code> and its number like this: <code>localhost:8000</code>. I want to know what's this and can I use it to access my host from my android device or some other PC as we do access Codecademy's localhost to learn AngularJS and Ruby on Rails. Pls help. Thanks in advance. :-)</p>
