Unlike some years back when sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Few people can build this sort of website completely from scratch though, so the handiest solution to have a dynamic website is to use a script application. Lots of web hosting companies offer script installers which can be used to add this sort of an app for each of your domain or subdomains, so you'll not have to set up anything manually. The main advantage of using an installer tool is that the scripts are available to use in just a few minutes and the copy which will be installed is already with the settings necessary for it to run efficiently on the specific hosting web server, so you will not need to change any script or account settings. That way you can quickly build one with simply a few clicks even if you have never had a site before.
