Having full root-level access means that you can access and change every file on a selected server, including all the system files, and to change system settings or set up server-side software that may be required by certain scripts and even offline applications to function effectively. A server is accessed at the root level with a root user, who has full privileges to do all the aforementioned tasks. Your root user can also generate various other users. For safety reasons, you are advised to have a different account for day-to-day tasks and to use the root account only if you actually need to do a particular task on the server. The root-level access feature will provide you with full control over your server from any kind of location, given that you know the user credentials.
