Unlike some years ago when Internet sites were almost exclusively static, the standard today is to have a feature-rich, dynamic website. Not many people can build this sort of web site completely from scratch though, hence the simplest solution to have a dynamic site is to use a script application. Many website hosting service providers offer script installers that you can use to add this type of an app for each of your domain name or subdomains, so you will not need to install anything manually. The main benefit of using an installer tool is the fact 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 necessary for it to run efficiently on the particular hosting server, so you'll not have to adjust any script or account settings. This way you can easily create one with just a few clicks even though you may have never had an Internet site before.
