An Operating System is the software which communicates with the hardware of a PC and works as the intermediary between applications and the hardware, which includes peripherals such as a printer, a computer mouse or a keyboard. When you run software, it sends requests to the OS using an API (Application Program Interface) and the communication is done through a command line or a Graphical User Interface (GUI). A lot like a personal computer, web hosting servers also use an Operating System that serves as a host for all of the software installed on them, including script applications or server-side software such as a flash server, a VOIP server, etc. A virtual machine can be created on a physical one, so you'll be able to install a guest OS on it and have a different system environment in contrast to the physical server host OS.
Multiple OS in VPS
We offer you as many as 3 different Linux distributions for the Operating System of our virtual private servers - Debian, CentOS and Ubuntu. These are among the most stable and reliable OSs on the market and we offer all three rather than just 1 because we realize that you might want to install some software that has specific requirements regarding the Operating System it'll run on. The latter is because each of the three Operating Systems has a huge support community behind it and there are various software programs you may install on the web hosting server. Your OS choice will also determine exactly what hosting Control Panel can be set up on the VPS if you wish to use one and for that reason we offer several Control Panels as well. In case you decide that you want a different OS, our technical support can quickly wipe the present one and install the one that you'd like. In addition, we offer an optional service to keep the OS on your VPS updated weekly.
