Each and every notebook or desktop or web server is run by an Operating System - the low-level software that communicates with the hardware, including peripherals such as a mouse and a printer, together with any applications that are installed on the 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 server, any app runs within the parameters set by the OS as well - priority, physical memory, processing time, etc. This is valid for both standard site scripts and server-side software like a media server. If a virtual server is set up on a physical one, there can be two separate Operating Systems, referred to as guest OS and host OS, so that you'll be able to set up a different software environment on the very same machine.
Multiple OS in Dedicated Hosting
The dedicated server solutions that we offer come with as many as three different Operating Systems to pick from. They are all Linux release - Ubuntu, CentOS and Debian, and not only do they have no license charges, but they’re also regarded as the most dependable and safe OSs. We provide three different ones as each one of them is backed by a different community. The packages that you could add on your web server are different and this could matter if you need to install some piece of software with specific requirements for the hosting environment. In this light, the hosting Control Panel that you can select for the dedicated server is also determined by the Operating System 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 once again with another one upon your request. As an optional service that you could add to the package at any moment, we can update your OS on a regular basis so as to keep it as secure as possible.
