Unlike some years ago when Internet sites were almost exclusively static, the standard nowadays is to have a feature-rich, dynamic Internet site. Few people can create this type of website completely from scratch though, so the simplest solution to have a dynamic website is to use a script application. Lots of hosting companies offer script installers which can be used 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 benefit of using an installer tool would be that the scripts are ready to use in a few minutes and the copy that will be installed is already with the settings required for it to run correctly on the particular hosting web server, so you will not need to modify any script or account settings. In this way you can easily create one with just a couple of clicks even though you may have never had a site before.
