An Operating System is the fundamental software that controls a computer system. It controls the way the hardware operates, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between the installed applications, plus the prioritization of applications when several run simultaneously. Each and every program that's installed on a PC operates by sending requests to the OS for various services by using an application program interface (API). The contact with the OS can be performed using a Graphical User Interface (GUI) or a command line. In the hosting world, the OS is what runs a server together with all the software installed on it, which includes not only website scripts, but also every other application such as a VOIP or a game server. In case there are virtual machines created, they use a guest OS that is run on the server host OS.
Multiple OS in Dedicated Servers
In case you decide to acquire one of our dedicated servers, you'll find three Operating Systems on the registration page because we want to give you a broader choice with regard to the system environment on the server as different applications can have particular requirements. CentOS, Ubuntu and Debian include different modules developed by their large support communities, so you can select each of these OSs and take advantage of a reliable and safe Internet hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you've selected at first doesn't meet the requirements of the software that you intend to run. We can also upgrade your OS routinely in order to keep it as risk-free as possible using our Managed Services upgrade package.
