Use the Add Application and the Edit Application dialog boxes to add an application to a site, or to edit an existing application. An application is a grouping of files that delivers content or provides services over protocols, such as HTTP. In addition to belonging to a site, an application belongs to an application pool, which isolates the application from applications in other application pools on the server. When you create an application in IIS, the application's path becomes part of the site's URL. You designate a directory as the application root, or starting point, for the application and then specify properties specific to that application.
