An Operating System is the basic software which controls a computer. It controls how the hardware functions, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between applications, and the prioritization of applications in case multiple ones run at the same time. Each program that is installed on a desktop or a laptop operates by sending requests to the OS for various services via an application program interface (API). The contact with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the web hosting field, the Operating System is what commands a server along with all of the software installed on it, which includes not only website scripts, but also any other application for example a VOIP or a game server. If there are virtual machines created, they use a guest OS that runs on the server host OS.
Multiple OS in Dedicated Servers
If you decide to get one of our dedicated servers, you shall find three Operating Systems on the registration page as we want to give you a wider choice regarding the system environment on the machine as different apps could have certain 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 stable and secure hosting service. Depending on your selection, you'll also have different Control Panels to choose from. Needless to say, we can always replace the Operating System if the one you have selected at first doesn't meet the requirements of the software that you would like to run. We can also upgrade the OS regularly in order to keep it as risk-free as possible using our Managed Services upgrade package.
