If you have root-level access to a server, this means that you will have full control over it. That is to say, you can set up any server-side app whatever the changes that it'll make to the software setting on the server, and you're able to both access and change any kind of file, which includes system files, and change any settings. This can be done by connecting to the server as a root user which has full privileges to perform all these things as well as to generate other users, which includes users that also have full privileges. This particular can be established with a web-based graphical interface or a Secure Shell console. For safety reasons, it's recommended that you create a separate user for your daily work and employ the root user only when you need to modify the server or to install software that may be needed by some script-driven application that you would like to run.

With the third Control Panel option that you'll be able to select on the order page - Hepsia, the root access is restricted.
