Unlike some years back when sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Not many 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 app. A lot of hosting providers offer script installers which you can use to add this kind of an app for any of your domain name or subdomains, so you'll not have to set up anything manually. The main advantage of using an installer tool would be that the scripts are ready to use within a few minutes and the copy that will be installed is already with the settings required for it to run the way it should on the particular hosting server, so you will not need to change any script or account settings. This way you can quickly build one with only a few mouse clicks even though you may have never had an Internet site before.
