An Operating System is the basic software which controls a PC. It controls the way the hardware functions, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between applications, as well as the prioritization of apps when several run simultaneously. Each program which is installed on a notebook or a desktop functions by sending requests to the OS for various services by using an application program interface (API). The interaction with the OS can be done via a Graphical User Interface (GUI) or a command line. In the hosting world, the Operating System is what commands a web hosting server along with any software installed on it, which includes not only website scripts, but also any other application such as a VOIP or a game server. When there are virtual machines created, they work with 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 larger choice with regard to the system environment on the machine as different applications can have specific requirements. CentOS, Ubuntu and Debian feature different modules developed by their vast support communities, so you can select any of these OSs and take advantage of a reliable and safe hosting service. Based on your choice, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you've selected initially doesn't meet the requirements of the software which you intend to run. We can also upgrade your OS regularly to keep it as secure as possible with our Managed Services upgrade package.
