Unlike some years back when web sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Not many people can create this kind of site from scratch though, so the most convenient solution to have a dynamic site is to use a script application. Lots of hosting service providers offer script installers which can be used to add this kind of an app for any of your domain name or subdomains, so you'll not have to install anything manually. The main advantage of using an installer tool would be that the scripts are available to use in just a couple of minutes and the copy that'll be set up is already with the settings required for it to run properly on the specific hosting web server, so you will not need to modify any script or account settings. This way you can quickly build one with only a few clicks even if you have never had an Internet site before.
