Having full root-level access means that you will be able to access and modify any kind of file on a selected server, which includes all the system files, and to change system settings or install server-side software that may be needed by certain scripts and even offline apps in order to work effectively. A server is accessed at the root level through a root user, which has full privileges to do any of the aforementioned tasks. Your root user can also make other users. For safety reasons, you are advised to have another account for routine tasks and to use the root account only if you actually need to perform a task on your hosting server. The root-level access function offers you full control of your server from any existing location, given that you have the user credentials.
Full Root-level Access in VPS Servers
You're able to control your new VPS servers at the root level whatever the package that you have picked, as long as the server is ordered with either the cPanel or the DirectAdmin web hosting Control Panel, or with no Control Panel at all. In the first case, a large number of system settings can be controlled from an easy to work with web-based interface, whereas in the second, you'll have to make everything via a console, unless you decide to install a Control Panel yourself. In either case, you'll have full control over the VPS as well as any kind of system and custom content on it at all times, that makes this kind of website hosting perfect for any app which you cannot run with a shared web hosting account because of the restricted level of access - frameworks, VoIP and audio/video streaming software, etc. The last VPS Control Panel alternative is Hepsia, but the root access to your server will be limited.
Full Root-level Access in Dedicated Servers
You'll have full root-level access to your dedicated server whatever the package you pick during the signup process, as long as the server is ordered with cPanel or DirectAdmin, or with no website hosting Control Panel at all. In all of these three cases, you can modify any part of the software environment in any way you find fit, that makes our server plans perfect for multi-media apps with specific requirements that cannot be covered if you use a shared web hosting account. The main difference between these options is the fact that when you select cPanel or DirectAdmin, you will have a web-based graphical interface to control numerous server-side options and any web content which you create or upload, while when you order the server devoid of Control Panel, you will have to do everything through a Secure Shell console or to set up a Control Panel of your own liking, if it's compatible with the Operating System that you have selected during the sign up process. With the final Control Panel option that you'll be able to choose on the order page - Hepsia, the root access is limited.
