An Operating System is the low-level software which controls a PC. It takes care of how the hardware behaves, the communication with peripherals including a monitor, a printer or a keyboard, the allocation of memory between all the applications, as well as the prioritization of apps in case several run concurrently. Each and every program that's installed on a laptop or a desktop functions by sending requests to the OS for different services by using an application program interface (API). The contact with the OS can be done via a Graphical User Interface (GUI) or a command line. In the Internet hosting world, the OS is what runs a hosting server as well as all of the software installed on it, which includes not only website scripts, but also every other application for instance a VOIP or a game server. In case there are virtual machines created, they work with a guest OS that is run on the server host OS.
Multiple OS in VPS Servers
In case you decide to go for one of our VPS server plans, you will be able to pick one of the three Linux releases which we supply for the OS of the servers - CentOS, Ubuntu and Debian. They're among the most preferred and most reliable server OSs out there and we offer them in order to give you a choice for the software environment of your machine if you wish to install some app with particular requirements regarding the packages that must be present on the web hosting server. We also offer three web hosting Control Panels and which one of them you can use will depend on the OS that you've picked. We leave the option to replace the server Operating System open, so when you want to use software that requires an OS different from the one you already have, 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 available.
Multiple OS in Dedicated Servers
The dedicated server solutions that we offer come with three different Operating Systems to pick from. They are all Linux distributions - Ubuntu, CentOS and Debian, and not only do they have no license fees, but they’re also known as the most stable and secure OSs. We supply three different ones since each of them is backed by a separate community. The packages which you could add on your server are different and this may matter in case you want to install some piece of software with specific requirements about the hosting environment. In this light, the hosting Control Panel which you can select for the dedicated server is also determined by the Operating System that you'll pick. You can select any of the three Operating Systems during the order procedure, however if needed, we can always install the server anew with another one upon your request. As an additional service that you could add to the plan at any time, we can update the OS regularly in order to keep it as secure as possible.
