An Operating System is the low-level software that manages a computer system. It takes care of how your hardware behaves, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between apps, and the prioritization of apps if several run at the same time. Each and every program which is installed on a PC functions by sending requests to the OS for various services via an application program interface (API). The interaction with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the web hosting field, the Operating System is what controls a hosting server together with all the software installed on it, which includes not only website scripts, but, in addition any other application for example a VOIP or a game server. When there're virtual machines created, they employ a guest OS which runs on the server host OS.
Multiple OS in Dedicated Servers
If you decide to purchase one of our dedicated servers, you'll find three Operating Systems on the registration page as we want to give you a broader choice for the system environment on the machine as different applications can have certain requirements. CentOS, Ubuntu and Debian feature different modules developed by their vast support communities, so you can select any of these OSs and enjoy a reliable and secure Internet hosting service. Based on your decision, you will also have different Control Panels to choose from. Of course, we can always change the Operating System if the one you have selected at first doesn't meet the requirements of the software that you'd like to run. We can also update your OS routinely in order to keep it as secure as possible using our Managed Services upgrade package.
