Having full root-level access means that you can access and change any file on a particular server, including all system files, and to change system settings or set up server-side software that may be necessary for specific scripts and even offline applications in order to work effectively. A server is accessed at the root level through a root user, which has full privileges to perform all of the aforementioned tasks. Your root user may also create various other users. For safety reasons, you are advised to have a separate account for daily tasks and to use the root account only if you actually need to perform a task on your server. The root-level access function provides you with full control over your server from any location, given that you have the user credentials.
