Application page is SharePoint

Introduction:
In this article we will discuss What are application pages in SharePoint 2010. You can visit a very good article on difference between site page and application pages in SharePoint 2010.

Description:
An application page is an .aspx file that is deployed physically inside the SharePoint Root directory under the following path. C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS.

An application page is different from a site page because it is not tracked by the content
database.
Ex: Setting page - settings.aspx

It is not for a particular site; rather, it can be used by any site within the farm.
You can access the page from the following URL: http://URL/_Layouts/settings.aspx

There is only one version of an application page scoped at the farm level, it can be compiled into a single assembly DLL and loaded into memory once for each Web application.

The default installation of SharePoint Server 2010 adds more than 400 application pages into the LAYOUTS directory. You can also visit step by steps to create Application Pages using Visual Studio 2010.
