An Operating System is the fundamental software that manages a PC. It controls how the hardware behaves, the communication with peripheral devices such as a monitor, a printer or a keyboard, the allocation of memory between various applications, plus the prioritization of apps in case several run at the same time. Every program that's installed on a PC operates by sending requests to the OS for various services via an application program interface (API). The communication with the OS can be done through a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what runs a web hosting server along with any 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.

Multiple OS in VPS

In case you select one of our virtual private server solutions, you'll have as many as three different Operating Systems to choose from - CentOS, Debian and Ubuntu. They're all Linux releases and we offer them instead of offering just one OS, as the applications that you might want to run on the server could have specific requirements about the software environment. Each of these three has certain advantages regarding the available plans that you may afterwards install, but what's common between them is that they are really stable and dependable and have vast communities that support them. The web hosting Control Panel choices for the VPS accounts depend on your OS choice, in order to give you more flexibility. If you order the virtual server with one OS and you need a different one later, our technical support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer the option to keep the Operating System on your server up-to-date weekly.
