An Operating System is the low-level software which controls a computer. It controls how the hardware operates, the communication with peripherals such as a monitor, a printer or a keyboard, the allocation of memory between your applications, along with the prioritization of applications in case several run concurrently. Every program that is installed on a PC works by sending requests to the OS for various services via an application program interface (API). The contact with the OS can be done using a Graphical User Interface (GUI) or a command line. In the Internet hosting field, the Operating System is what runs a hosting server together with all the software installed on it, which includes not only website scripts, but, in addition every other application for example a VOIP or a game server. If there're virtual machines created, they use a guest OS which runs on the server host OS.
Multiple OS in Dedicated Servers
We offer three Operating Systems with our dedicated server packages - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are freely available so they will not increase the cost of your new web hosting server, but also because they are outstandingly secure and stable. Each one of them is supported by a big community of developers, so you'll be able to choose from a large number software packages that you may install on your server if the app that you would like to work with has specific requirements. The Operating System will also determine what hosting Control Panel you can use since the Control Panels that we offer are compatible with particular OSs only and since we would like to provide you with as much adaptability as possible, we offer a couple of OSs and multiple Control Panels. In case you get a server with a given OS, we will change it upon request in the event that it turns out that you will need alternative one. We will also keep the OS updated weekly as a part of our optional Managed Services upgrade.
