Every single notebook or desktop or web server is run by an Operating System - the low-level program that communicates with the hardware, including peripherals such as a mouse and a printer, as well as any applications that are currently installed on your 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 Operating System. On a web server, each and every app runs within the parameters specified by the OS as well - priority, physical memory, processing time, etcetera. This is valid for both standard Internet site scripts and server-side software such as a media server. If a virtual server is set up on a physical one, there can be two separate Operating Systems, named guest OS and host OS, which means that you can set up a different software environment on a single machine.
Multiple OS in Dedicated Hosting
The dedicated servers that we offer come with as many as three different Operating Systems because we want to give you more flexible packages which will allow you to install and run any web software irrespective of its system requirements. The options are CentOS, Debian and Ubuntu and these three OSs are among the most dependable and safe ones, not mentioning that they don't have any kind of license charges. All three have numerous developers who have created numerous software packages that you'll be able to install and use on your web server. We also offer three internet hosting Control Panels and which one you can use is determined by the Operating System that you choose when you sign up. If you need another OS later on, it won't be a problem as we can always reinstall your server. With our Managed Services package we can also keep your OS secure by updating it on a weekly basis with all patches that are released for it.
