Having full root-level access signifies that you will be able to access and change each file on a selected server, including all of the system files, and to change system settings or install server-side software that may be required by specific scripts and even offline apps to function effectively. A server is accessed at the root level via a root user, who has full privileges to perform all the abovementioned things. The root user may also generate various other users. For safety reasons, you are advised to have a different account for daily tasks and to use the root account only if you actually need to perform a particular task on your website hosting server. The root-level access feature provides you with full control over your server from almost any location, as long as you have the user credentials.
