An Operating System is the software which communicates with the hardware of a computer and works as the intermediary between apps and the hardware, including 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 interaction is done through a command line or a Graphical User Interface (GUI). Just like a personal computer, web servers also feature an Operating System that functions as a host for any 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'll be able 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

If you decide to buy one of our dedicated servers, you'll find three Operating Systems on the order page because we want to give you a larger choice for the system environment on your server as different apps can have specific 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 safe web hosting service. Based on your selection, you'll also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you've selected at first doesn't meet the requirements of the software that you'd like 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.
