An Operating System is the basic software which manages a computer system. It controls how the hardware functions, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between apps, as well as the prioritization of applications if several run concurrently. Every program that's installed on a computer operates by sending requests to the OS for different services using an application program interface (API). The interaction with the OS is possible via a Graphical User Interface (GUI) or a command line. In the hosting field, the Operating System is what runs a web server as well as all of the software installed on it, which includes not only website scripts, but, in addition every other application for example a VOIP or a game server. When there're virtual machines created, they work with a guest OS that is run on the server host OS.
Multiple OS in Dedicated Hosting
In case you decide to acquire one of our dedicated servers, you will find three Operating Systems on the order page since we want to give you a larger choice with regard to the system environment on the machine as different applications may have certain requirements. CentOS, Ubuntu and Debian contain different modules developed by their huge support communities, so you can select any of these OSs and enjoy a stable and safe hosting service. Depending on your decision, you will also have different Control Panels to choose from. Of course, we can always change the Operating System in case the one you have selected initially doesn't meet the requirements of the software which you want to run. We can also update the OS routinely in order to keep it as secure as possible with our Managed Services upgrade package.
