An Operating System is the fundamental software that controls a PC. It takes care of the way your hardware behaves, the communication with peripheral devices like a monitor, a printer or a keyboard, the allocation of memory between apps, plus the prioritization of apps when several run simultaneously. Each and every program that is installed on a computer works by sending requests to the OS for various services using 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 world, the OS is what commands a server and all of the software installed on it, which includes not only website scripts, but, in addition every other application such as a VOIP or a game server. In case there're virtual machines created, they use a guest OS that is run on the server host OS.
