An Operating System is the software that communicates with the hardware of a PC and serves 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 app, it transfers 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). A lot like a personal computer, web hosting servers also use an Operating System that functions as a host for any software installed on them, which includes script applications or server-side software such as a flash server, a VOIP server, and so on. A virtual machine can be set up on a physical one, so it is possible to install a guest OS on it and have a different system environment in contrast to the physical server host Operating System.

Multiple OS in Dedicated Servers

In case you decide to obtain one of our dedicated servers, you will find three Operating Systems on the order page because we want to give you a broader choice regarding the system environment on your machine as different applications can have particular requirements. CentOS, Ubuntu and Debian contain different modules developed by their huge support communities, so you can select any of these OSs and benefit from a stable and risk-free web hosting service. Depending on your choice, you'll also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you've selected initially does not meet the requirements of the software which you want to run. We can also upgrade your OS regularly to keep it as secure as possible with our Managed Services upgrade package.
