An Operating System is the software that communicates with the hardware of a PC and functions as the intermediary between the installed applications and the hardware, which includes peripherals such as a printer, a mouse or a keyboard. When you run software, it transmits requests to the OS through an API (Application Program Interface) and the contact is done through a command line or a Graphical User Interface (GUI). Similar to a personal computer, web servers also feature an Operating System that acts as a host for the software installed on them, which includes script apps or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be generated on a physical one, so you could install a guest OS on it and have a different system environment in contrast with the physical server host Operating System.

Multiple OS in Dedicated Servers

In case you decide to purchase one of our dedicated servers, you will find three Operating Systems on the order page as we want to give you a larger choice regarding the system environment on the server as different applications can have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select each of these OSs and enjoy a reliable and safe hosting service. Based on your choice, you will also have different Control Panels to choose from. Of course, we can always change the Operating System in case the one you've selected in the beginning doesn't meet the requirements of the software which you would like to run. We can also update the OS on a regular basis in order to keep it as risk-free as possible with our Managed Services upgrade package.
