An Operating System is the fundamental software that manages a PC. It controls how your hardware operates, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between the installed applications, along with the prioritization of applications if multiple ones run concurrently. Every program that's installed on a PC functions by sending requests to the OS for different services via an application program interface (API). The interaction with the OS can be done using a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the Operating System is what commands a web server as well as any software installed on it, which includes not only website scripts, but, in addition any other application for instance a VOIP or a game server. If there are virtual machines created, they employ a guest OS which runs on the server host OS.
Multiple OS in Dedicated Web Hosting
In case you decide to obtain one of our dedicated servers, you shall 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 come with 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 selection, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System in case the one you have selected in the beginning doesn't meet the requirements of the software that you'd like to run. We can also upgrade your OS routinely to keep it as secure as possible through our Managed Services upgrade package.
