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