Having full root-level access signifies that you will be able to access and update any kind of file on a particular server, in addition to all of the system files, and to change system settings or set up server-side software that may be necessary for specific scripts and even offline applications to function efficiently. A server is accessed at the root level via a root user, which has full privileges to do all the aforementioned things. The root user may also make various other users. For security reasons, you are advised to have a different account for everyday tasks and to use the root account only if you actually need to perform a specific task on your website hosting server. The root-level access feature will provide you with full control of your server from any location, as long as you have the user credentials.
