An Operating System is the software that communicates with the hardware of a PC and functions as the intermediary between all the applications and the hardware, which includes peripheral devices such as a printer, a computer mouse or a keyboard. When you run an application, it transfers requests to the OS using an API (Application Program Interface) and the communication is done via a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also have an Operating System which acts as a host for the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, etcetera. A virtual machine can be set up on a physical one, so you can 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 Hosting

In case you decide to buy one of our dedicated servers, you will find three Operating Systems on the registration page as we want to give you a broader choice regarding the system environment on your server as different apps can have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their large support communities, so you can select each of these OSs and take advantage of a stable and safe web hosting service. Based on your selection, you'll 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 intend to run. We can also upgrade your OS routinely in order to keep it as risk-free as possible using our Managed Services upgrade package.
