Unlike some years ago when Internet sites were almost exclusively static, the standard currently is to have a feature-rich, dynamic site. Not everybody can build this type of site from scratch though, therefore the most convenient solution to have a dynamic website is to use a script application. A lot of hosting service providers offer script installers you can use to add this sort of an application for any of your domain name or subdomains, so you'll not have to add anything manually. The main benefit of using an installer tool is the fact that the scripts are ready to use within a couple of minutes and the copy that'll be installed is already with the settings required for it to run the way it should on the particular hosting web server, so you will not need to modify any script or account settings. This way you can easily create one with simply a couple of mouse clicks even if you have never had an Internet site before.
