An Operating System is the basic software which manages a computer system. It takes care of the way your hardware behaves, the communication with peripheral devices for instance a monitor, a printer or a keyboard, the allocation of memory between apps, as well as the prioritization of apps if multiple ones run at the same time. Any program which is installed on a desktop or a laptop works by sending requests to the OS for different services using an application program interface (API). The contact with the OS can be achieved using a Graphical User Interface (GUI) or a command line. In the web hosting world, the Operating System is what commands a hosting server along with any software installed on it, which includes not only website scripts, but also any 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 VPS Hosting
If you choose to purchase one of our virtual private server packages, you'll be able to opt for one of the three Linux releases that we supply for the Operating System of the servers - CentOS, Ubuntu and Debian. They are among the most popular and most dependable server OSs out there and we offer them in order to give you a choice for the software environment of your machine in case that you need to install some application with precise requirements regarding the packages that should be present on the hosting server. We also offer three internet hosting Control Panels and which one of them you'll be able to use will depend on the OS that you've chosen. We leave the chance to change the server Operating System open, so when you want to use software that requires an OS different from the one that's already present, we can always re-install 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 released.
Multiple OS in Dedicated Web Hosting
In case you decide to obtain one of our dedicated servers, you'll find three Operating Systems on the order page since we want to give you a larger choice for the system environment on your machine as different apps could have particular requirements. CentOS, Ubuntu and Debian feature different modules developed by their vast support communities, so you can select each of these OSs and enjoy a stable and safe web hosting service. Depending on your choice, you will also have different Control Panels to choose from. Needless to say, we can always change the Operating System in case the one you have selected initially does not meet the requirements of the software which you'd like to run. We can also update the OS routinely in order to keep it as secure as possible through our Managed Services upgrade package.
