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 communication is done through a command line or a Graphical User Interface (GUI). Identical to a personal computer, web servers also have an Operating System that acts as a host for any software installed on them, including script apps or server-side software such as a flash server, a VOIP server, and many others. A virtual machine can be created 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 Web Hosting
If you decide to get one of our dedicated servers
, you shall find three Operating Systems on the order page since we want to give you a broader choice regarding the system environment on your machine as different applications could have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their vast support communities, so you can select any of these OSs and enjoy a reliable and safe Internet hosting service. Depending on your selection, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System in case the one you have selected in the beginning does not meet the requirements of the software which you want to run. We can also update your OS on a regular basis in order to keep it as risk-free as possible through our Managed Services upgrade package.
