An Operating System is the fundamental software which controls a computer system. It controls the way your hardware behaves, the communication with peripheral devices like a monitor, a printer or a keyboard, the allocation of memory between your applications, and the prioritization of apps if several run simultaneously. Each program that is installed on a laptop or a desktop works 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 field, the Operating System is what controls a server and all of the software installed on it, which includes not only website scripts, but also every other application for instance a VOIP or a game server. When there're virtual machines created, they employ a guest OS that is run on the server host OS.

Multiple OS in Dedicated Servers

In case you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the order page since we want to give you a wider choice for the system environment on the machine as different apps can have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select any of these OSs and enjoy a stable and secure hosting service. Based on your choice, you will also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you've selected in the beginning does not meet the requirements of the software that you want to run. We can also update the OS regularly in order to keep it as risk-free as possible through our Managed Services upgrade package.
