An Operating System is the fundamental software which controls a computer. It handles how the hardware functions, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between various applications, plus the prioritization of applications when several run at once. Every program which is installed on a desktop or a laptop works by sending requests to the OS for different services using an application program interface (API). The interaction with the OS can be performed via a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the Operating System is what commands a hosting server along with all the software installed on it, which includes not only website scripts, but, in addition any other application such as a VOIP or a game server. If there're virtual machines created, they employ a guest OS which is run on the server host OS.
Multiple OS in Dedicated Web Hosting
In case you decide to obtain one of our dedicated servers, you will find three Operating Systems on the order page as we want to give you a broader choice regarding the system environment on your machine as different applications may have certain requirements. CentOS, Ubuntu and Debian include different modules developed by their vast support communities, so you can select each of these OSs and enjoy a reliable and risk-free web hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you have selected in the beginning does not meet the requirements of the software that you want to run. We can also upgrade the OS routinely to keep it as risk-free as possible through our Managed Services upgrade package.
