An Operating System is the low-level software that manages a computer system. It takes care of how your hardware behaves, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between all the applications, along with the prioritization of applications if multiple ones run at once. Each program that's installed on a PC functions by sending requests to the OS for different services by using an application program interface (API). The communication with the OS can be performed via a Graphical User Interface (GUI) or a command line. In the hosting world, the OS is what runs a web server and all the software installed on it, which includes not only website scripts, but, in addition any other application for example a VOIP or a game server. If there're virtual machines created, they use a guest OS that is run on the server host OS.

Multiple OS in VPS Servers

If you choose to go for one of our VPS server packages, you shall be able to select one of the three Linux distributions that we offer for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most well-known and most stable server OSs available on the market and we offer them in order to give you a choice for the software environment of your machine in case that you intend to install some app with particular requirements in terms of the packages that should be present on the web hosting server. We also offer three web hosting Control Panels and which one of them you may use depends on the OS that you've picked. We leave the possibility to change the server Operating System open, so when you want to use software that requires an OS different from the one that's already present, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing all of the security updates which may be released.
