An Operating System is the low-level software which manages a PC. It controls the way your hardware functions, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between all the applications, as well as the prioritization of applications when several run concurrently. Any program that is installed on a notebook or a desktop works by sending requests to the OS for various services via an application program interface (API). The communication with the OS can be achieved via a Graphical User Interface (GUI) or a command line. In the Internet hosting field, the Operating System is what commands a web server and all 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're virtual machines created, they employ a guest OS which is run on the server host OS.

Multiple OS in Dedicated Servers

If you decide to buy one of our dedicated servers, you will find three Operating Systems on the order page as we want to give you a wider choice for the system environment on the machine as different applications can have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their huge support communities, so you can select any of these OSs and enjoy a reliable and risk-free hosting service. Depending on your decision, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System in case the one you've selected in the beginning doesn't meet the requirements of the software that you would like to run. We can also upgrade the OS on a regular basis in order to keep it as risk-free as possible using our Managed Services upgrade package.
