An Operating System is the software that communicates with the hardware of a computer and is the intermediary between the installed applications and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run an application, it transmits 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). Similar to a personal computer, web servers also feature an Operating System which serves as a host for 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 Hosting
In case you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the order page because we want to give you a wider choice regarding the system environment on your machine as different apps could have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their large support communities, so you can select any of these OSs and enjoy a reliable and secure web hosting service. Based on your decision, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you've selected in the beginning does not meet the requirements of the software which you would like to run. We can also update your OS on a regular basis to keep it as risk-free as possible using our Managed Services upgrade package.
