All on one page?

[Lukermsdn111]

I am a beginner in this field so this may be a dumb question but Im gonna go ahead with it anyway :)

Im not sure how to articulate it so an examples probably best:

On http://www.deviantart.com/ you can select to view 'newest' and 'popular' pictures.
When you click these options an entirely new page isnt loaded - what is used to make this possible?

This is done with AJAX, basically, you use JavaScript to reload only a small part of the page. If you would like to do something like this you will need to learn JavaScript. You can use frameworks such as JQuery to faciliate the process.
