This article will focus on the concepts of the two main page types that can be found in SharePoint 2007 (WSS): Application pages and Site pages. Since this is a WSS level objective, as opposed to MOSS, you will not need MOSS to review the information provided. Windows Server 2003, WSS and Visual Studio 2005 are all that is needed, with no additional add-ons.

There are two primary types of pages found in a WSS application, Application pages and Site pages. The first type, Application Pages, is generally aspx pages that you will find used across multiple Sites. They are usually the "behind the scenes" administrative type pages. Secondly, Site Pages, are the pages that are used inside an individual site. These are mainly the user level pages that make up the site, for example, the index page. When you enter a site as a user you will probably be viewing Site Pages (like Default.Aspx). In the same way, when you use the administrative pages of a site (like Settings.Aspx), you will likely be working with Application Pages.
