Unlike some years back when sites were almost exclusively static, the standard currently is to have a feature-rich, dynamic Internet site. Few people can create this sort of site completely from scratch though, hence the handiest solution to have a dynamic website is to use a script application. Lots of hosting providers offer script installers that can be used to add such an application for any of your domain or subdomains, so you'll not have to install anything manually. The advantage of using an installer tool is the fact that the scripts are ready to use in just a few minutes and the copy that will be set up is already with the settings required for it to run properly on the particular hosting server, so you'll not need to modify any script or account settings. That way you can quickly create one with only a few clicks even if you have never had a website before.
