An Operating System is the basic software that manages a PC. It handles how the hardware behaves, the communication with peripheral devices like a monitor, a printer or a keyboard, the allocation of memory between your applications, along with the prioritization of applications if several run concurrently. Each program that's installed on a PC works by sending requests to the OS for different services using an application program interface (API). The interaction with the OS can be achieved using a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the OS is what controls a hosting server and all the software installed on it, which includes not only website scripts, but, in addition every other application for instance a VOIP or a game server. When there're virtual machines created, they use a guest OS that runs 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 registration page as we want to give you a wider choice for the system environment on the server as different applications could have specific 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 reliable and secure web hosting service. Depending on your choice, you will also have different Control Panels to choose from. Of course, we can always replace the Operating System if the one you have selected in the beginning doesn't meet the requirements of the software which you'd like to run. We can also update your OS regularly in order to keep it as secure as possible with our Managed Services upgrade package.
