Every single PC or server is run by an Operating System - the low-level program that communicates with the hardware equipment, including peripheral devices such as a mouse and a printer, along with any applications that are currently installed on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the Operating System. On a server, each application runs within the parameters set by the OS as well - priority, physical memory, processing time, and so on. This is valid for both standard site scripts and server-side software such as a media server. If a virtual server is set up on a physical one, there can be two separate Operating Systems, named guest OS and host OS, so that you can set up a different software environment on the very same machine.

Multiple OS in Dedicated Servers Hosting

If you decide to purchase one of our dedicated servers, you will find three Operating Systems on the registration page because we want to give you a larger choice for the system environment on your server as different apps could have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select any of these OSs and benefit from a stable and secure Internet hosting service. Based on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected in the beginning does not meet the requirements of the software that you would like to run. We can also update your OS regularly to keep it as risk-free as possible through our Managed Services upgrade package.
