An Operating System is the basic software which controls a PC. It handles the way your hardware behaves, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between all the applications, plus the prioritization of applications when multiple ones run at the same time. Each program which is installed on a notebook or a desktop operates by sending requests to the OS for different services using an application program interface (API). The communication with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the OS is what controls a web server and any software installed on it, which includes not only website scripts, but, in addition every other application for instance a VOIP or a game server. If there're virtual machines created, they employ a guest OS that runs on the server host OS.
Multiple OS in Dedicated Web Hosting
In case you decide to buy one of our dedicated servers, you shall find three Operating Systems on the registration page since we want to give you a broader choice for the system environment on the machine as different apps can have certain requirements. CentOS, Ubuntu and Debian include different modules developed by their huge support communities, so you can select each of these OSs and benefit from a stable and safe web hosting service. Based on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System in case the one you've selected in the beginning doesn't meet the requirements of the software that you would like to run. We can also upgrade the OS regularly to keep it as secure as possible with our Managed Services upgrade package.
