An Operating System is the low-level software which manages a computer system. It takes care of the way your hardware operates, the communication with peripheral devices such as a monitor, a printer or a keyboard, the allocation of memory between applications, and the prioritization of apps when several run concurrently. Each program that is installed on a desktop or a notebook functions by sending requests to the OS for different services via an application program interface (API). The contact with the OS can be done using a Graphical User Interface (GUI) or a command line. In the hosting field, the OS is what commands a server as well as all the software installed on it, which includes not only website scripts, but also any other application for instance a VOIP or a game server. In case there are virtual machines created, they use a guest OS which runs 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 as we want to give you a larger choice for the system environment on the server as different applications can have specific requirements. CentOS, Ubuntu and Debian contain different modules developed by their vast support communities, so you can select any of these OSs and benefit from a reliable and secure web hosting service. Based on your decision, you'll also have different Control Panels to choose from. Of course, we can always replace the Operating System if 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 in order to keep it as risk-free as possible through our Managed Services upgrade package.
