Having full root-level access signifies that you will be able to access and update every file on a particular server, which includes all the system files, and to change system settings or set up server-side software that may be required by certain scripts and even offline apps to function effectively. A server is accessed at the root level with a root user, which has full privileges to do all the abovementioned things. Your root user may also create various other users. For security reasons, you're advised to have a separate 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 will give you full control over your server from any kind of location, provided that you know the user credentials.
Full Root-level Access in VPS Servers
You will be able to manage your new VPS servers at the root level whatever the package that you have chosen, 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 lot of system settings can be managed from an easy to navigate web-based interface, whereas in the second, you'll need to do everything via a console, until you decide to set up a Control Panel yourself. Either way, you will have full control over the VPS as well as any system and / or custom content on it all of the time, that makes this type of website hosting perfect for any app which you cannot run with a shared web hosting account due to the restricted level of access - frameworks, VoIP and audio/video streaming software, etc. The final VPS Control Panel option is Hepsia, however the root access to your server will be restricted.
Full Root-level Access in Dedicated Servers
You'll have full root-level access to your dedicated server whatever the package you choose during the registration process, as long as the server is provided with cPanel or DirectAdmin, or without hosting Control Panel at all. In all of these 3 cases, you'll be able to update any part of the software environment in any way you find fit, that makes our server packages suitable for multi-media applications with specific requirements that cannot be covered if you use a shared website hosting account. The main difference between these options is that when you pick cPanel or DirectAdmin, you'll have a web-based graphical interface to control various server-side options as well as any site content which you create or upload, whereas when you order the server devoid of Control Panel, you'll have to do everything with a Secure Shell console or to set up a Control Panel of your liking, if it's compatible with the OS that you have chosen during the sign up process. With the final Control Panel option that you will be able to choose on the order page - Hepsia, the root access is restricted.
