An Operating System is the low-level software that controls a PC. It handles the way the hardware functions, the communication with peripheral devices for instance a monitor, a printer or a keyboard, the allocation of memory between apps, along with the prioritization of apps if multiple ones run simultaneously. Each and every program that's installed on a computer works by sending requests to the OS for different services by 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 web hosting world, the OS is what commands a web server as well as 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. In case there're virtual machines created, they use a guest OS that runs on the server host OS.
Multiple OS in Dedicated Hosting
The dedicated servers that we offer can be set up with as many as three different Operating Systems because we want to offer you more flexible solutions that will enable you to install and run any web software whatever its system requirements. The options are CentOS, Debian and Ubuntu and these three OSs are among the most stable and safe ones, not mentioning that they don't have any license fees. All three have a large number of developers that have created countless software packages that you could install and use on your server. We also offer three hosting Control Panels and which one you can use depends on the Operating System that you choose when you register. In case you need some other OS afterwards, it will not be a problem because we can always reinstall your machine. With our Managed Services package we can also keep your OS secure by upgrading it on a weekly basis with any patches which are available for it.
