An Operating System is the low-level software that controls a computer. It controls the way your hardware behaves, the communication with peripheral devices for instance a monitor, a printer or a keyboard, the allocation of memory between all the applications, as well as the prioritization of applications if several run concurrently. Each program which is installed on a desktop or a notebook operates by sending requests to the OS for various services using an application program interface (API). The contact with the OS can be done via a Graphical User Interface (GUI) or a command line. In the web hosting world, the OS is what controls a web server as well as any software installed on it, which includes not only website scripts, but also every other application such as a VOIP or a game server. If 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 shall find three Operating Systems on the order page because we want to give you a broader choice regarding the system environment on your machine as different apps could have particular requirements. CentOS, Ubuntu and Debian come with different modules developed by their large support communities, so you can select any of these OSs and take advantage of a reliable and risk-free Internet hosting service. Based on your decision, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System if the one you have selected at first does not meet the requirements of the software which you want to run. We can also update the OS routinely in order to keep it as risk-free as possible through our Managed Services upgrade package.
