An Operating System is the fundamental software that manages a PC. It controls the way your hardware operates, the communication with peripheral devices for instance a monitor, a printer or a keyboard, the allocation of memory between various applications, plus the prioritization of apps in case several run simultaneously. Every program which is installed on a desktop or a notebook functions by sending requests to the OS for various services via an application program interface (API). The contact with the OS can be done using a Graphical User Interface (GUI) or a command line. In the web hosting world, the OS is what runs a hosting server and all of the software installed on it, which includes not only website scripts, but also every other application for example a VOIP or a game server. When there're virtual machines created, they work with a guest OS that is run on the server host OS.

Multiple OS in Dedicated Servers 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 broader choice for the system environment on your server as different apps can have certain requirements. CentOS, Ubuntu and Debian contain 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. Depending on your decision, you'll also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you have selected initially doesn't meet the requirements of the software that you would like to run. We can also upgrade your OS routinely in order to keep it as secure as possible using our Managed Services upgrade package.
