If you have root-level access to a hosting server, this means that you will have full control of it. That is to say, you can install any server-side app no matter what the changes that it will make to the software environment on the server, and you can both access and modify 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 that has full privileges to do the aforementioned things as well as to make other users, which includes users that also have full privileges. This connection can be established through a web-based graphical interface or a Secure Shell console. For safety reasons, it's recommended that you make one more user for your daily work and employ the root user only when you need to modify the server or to set up software that may be needed by some script-driven application that you wish to run.

Full Root-level Access in VPS Servers

You are able to take care of your new VPS servers at the root level regardless of the package that you have selected, as long as the server is ordered with either the cPanel or the DirectAdmin hosting Control Panel, or without any Control Panel at all. In the first case, a large number of system settings can be controlled from an intuitive web-based interface, whereas in the second, you'll need to make everything through a console, until you decide to set up a Control Panel yourself. In either case, you will have full control over the VPS in addition to any system or custom content on it all the time, that makes this kind of website hosting perfect for any application which you can't run with a shared web hosting account because of the limited degree of access - frameworks, VoIP and audio/video streaming software, and so on. The last VPS Control Panel alternative is Hepsia, but the root access to your server will be limited.
