An Operating System is the low-level software which controls a computer. It controls how your hardware functions, the communication with peripheral devices including a monitor, a printer or a keyboard, the allocation of memory between apps, plus the prioritization of applications if multiple ones run simultaneously. Any program that is installed on a notebook or a desktop functions by sending requests to the OS for different services via an application program interface (API). The contact with the OS can be performed via a Graphical User Interface (GUI) or a command line. In the hosting world, the OS is what commands a server along with any software installed on it, which includes not only website scripts, but, in addition every other application for instance a VOIP or a game server. When there're virtual machines created, they work with a guest OS which runs on the server host OS.
Multiple OS in VPS Servers
In case you decide to acquire one of our VPS server
packages, you shall 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 stable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you want to install some app with particular requirements regarding the packages that need to be present on the web hosting server. We also offer three internet hosting Control Panels and which one of them you could use will depend on the OS that you've chosen. We leave the chance to replace the server Operating System open, so if you want to use software that requires an OS different from the one you have, we can always reinstall the VPS. We can also keep the OS up-to-date weekly by installing any security updates which may be released.
Multiple OS in Dedicated Servers
The dedicated server
plans that we offer come with as many as three different Operating Systems to choose from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license taxes, but they are also known as the most stable and safe OSs. We offer three different ones since each of them is backed by a different community. The packages which you can add on your hosting server are different and this could matter in case you want to install some piece of software with particular requirements regarding the hosting environment. In this light, the internet hosting Control Panel which you can select for the dedicated server also depends on the OS that you'll choose. You can pick any of the three Operating Systems throughout the order procedure, but if necessary, we can always set up the server anew with an alternative one upon your request. As an optional service that you may add to the plan any time, we can update the OS on a regular basis in order to keep it as secure as possible.
