An Operating System is the fundamental software which manages a PC. It takes care of how your hardware operates, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between apps, and the prioritization of apps if several run at once. Any program that's installed on a desktop or a notebook works by sending requests to the OS for different services using an application program interface (API). The interaction with the OS can be performed through a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what controls a server and all the software installed on it, which includes not only website scripts, but, in addition every other application such as a VOIP or a game server. In case there're virtual machines created, they work with a guest OS that runs on the server host OS.
Multiple OS in Dedicated Servers Hosting
In case you decide to get one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a broader choice regarding the system environment on your server as different apps could have particular requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select any of these OSs and take advantage of a reliable and secure Internet hosting service. Based on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected initially doesn't meet the requirements of the software which you intend to run. We can also update your OS on a regular basis to keep it as secure as possible using our Managed Services upgrade package.
