Unlike some years back when websites were almost exclusively static, the standard currently is to have a feature-rich, dynamic site. Not many people can create this kind of web site from scratch though, therefore the simplest solution to have a dynamic website is to use a script app. Many web hosting providers offer script installers which can be used to add such an application for each of your domain or subdomains, so you will not need to set up anything manually. The main benefit of using an installer tool is the fact that the scripts are available to use within a few minutes and the copy that'll be installed is already with the settings required for it to run efficiently on the particular hosting server, so you will not have to adjust any script or account settings. In this way you can quickly create one with simply a couple of mouse clicks even though you may have never had an Internet site before.
