An Operating System is the basic software which controls a PC. It takes care of how the hardware behaves, the communication with peripherals including a monitor, a printer or a keyboard, the allocation of memory between your applications, plus the prioritization of applications if multiple ones run simultaneously. Each and every program that's installed on a notebook or a desktop operates by sending requests to the OS for various services via an application program interface (API). The communication with the OS can be done through a Graphical User Interface (GUI) or a command line. In the web hosting field, the Operating System is what runs a web server along with all the software installed on it, which includes not only website scripts, but, in addition any other application such as a VOIP or a game server. In case there're virtual machines created, they use a guest OS that runs on the server host OS.
Multiple OS in Dedicated Servers Hosting
In case you decide to buy one of our dedicated servers, you shall find three Operating Systems on the registration page because we want to give you a wider choice with regard to the system environment on your machine as different applications may have certain requirements. CentOS, Ubuntu and Debian feature different modules developed by their large support communities, so you can select each of these OSs and enjoy a stable and safe Internet hosting service. Depending on your choice, you will also have different Control Panels to choose from. Needless to say, we can always replace the Operating System in case the one you have selected at first does not meet the requirements of the software that you want to run. We can also update your OS routinely to keep it as secure as possible with our Managed Services upgrade package.
