An Operating System is the software that interacts with the hardware of a PC and serves 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 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). A lot like a personal computer, web hosting servers also feature an Operating System that functions as a host for all the 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 you will be able to install a guest OS on it and have a different system environment in contrast to the physical server host OS.
Multiple OS in Dedicated Servers Hosting
If you decide to buy one of our dedicated servers
, you shall find three Operating Systems on the order page as we want to give you a broader choice with regard to the system environment on your machine as different apps may have particular requirements. CentOS, Ubuntu and Debian contain different modules developed by their vast support communities, so you can select each of these OSs and enjoy a reliable and safe Internet hosting service. Based on your choice, you'll also have different Control Panels to choose from. Needless to say, 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 that you'd like to run. We can also upgrade your OS on a regular basis in order to keep it as secure as possible with our Managed Services upgrade package.
