An Operating System is the basic software that controls a computer system. It takes care of how your hardware functions, the communication with peripherals like a monitor, a printer or a keyboard, the allocation of memory between applications, and the prioritization of apps if multiple ones run concurrently. Each and every program that's installed on a PC functions by sending requests to the OS for different services via an application program interface (API). The contact with the OS can be done via a Graphical User Interface (GUI) or a command line. In the hosting world, the Operating System is what commands a web server and all of 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. In case there're virtual machines created, they work with a guest OS that is run on the server host OS.
Multiple OS in VPS Servers
In case you decide to buy one of our VPS server
plans, you will be able to select one of the three Linux releases that we supply for the OS of the servers - CentOS, Ubuntu and Debian. These are among the most well-known and most stable server OSs available and we offer them so that you have a choice for the software environment of your machine if you intend to install some app with particular requirements with regards to the packages that have to be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you can use depends on the OS that you have chosen. We leave the possibility to replace the server Operating System open, so when you want to use software that requires an OS different from the one you have, we can always reinstall the VPS. We can also keep the OS up-to-date on a weekly basis by installing all of the security updates that may be available.
