Each PC or server is run by an Operating System - the low-level program which communicates with the hardware equipment, including peripheral devices such as a mouse or a printer, and any applications that are present on your system. Any program input using a command line or a Graphical User Interface (GUI) is processed by sending an Application Program Interface (API) request to the OS. On a web server, every single application runs within the parameters specified by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard website scripts and server-side software like a media server. In case a virtual server is set up on a physical one, there can be two independent Operating Systems, referred to as guest OS and host OS, so that you will be able to set up a different software environment on the very same machine.
Multiple OS in Dedicated Servers Hosting
We offer three Operating Systems with our dedicated server plans - CentOS, Ubuntu and Debian. They're all different Linux distributions and we offer them not only because they are 100 % free and they will not increase the price of your new hosting server, but also because they are exceptionally secure and stable. Each of them is supported by a huge community of web developers, so you'll be given the option to choose from a myriad of software packages that you could install on your server if the app that you would like to employ has certain requirements. The Operating System will also determine what web hosting Control Panel you can use as the Control Panels that we offer run on specific OSs only and because we would like to provide you with as much flexibility as possible, we offer a couple of OSs and multiple Control Panels. If you choose a server with a given OS, we could change it upon request if it turns out that you will need a different one. We can also keep the OS updated on a weekly basis as a part of our additional Managed Services upgrade.
