An Operating System is the software that communicates with the hardware of a computer system and functions as the intermediary between all the applications and the hardware, including peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it transmits requests to the OS using 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, hosting servers also have an Operating System which serves as a host for all the software installed on them, including script apps or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be set up on a physical one, so you will 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 Hosting
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 broader choice for the system environment on the server as different applications may have specific requirements. CentOS, Ubuntu and Debian come with different modules developed by their huge support communities, so you can select any of these OSs and benefit from a reliable and safe hosting service. Depending on your choice, you'll also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you've selected initially doesn't meet the requirements of the software which you intend to run. We can also upgrade your OS regularly in order to keep it as risk-free as possible using our Managed Services upgrade package.
