An Operating System is the low-level software that manages a computer system. It handles how the hardware functions, the communication with peripherals for instance a monitor, a printer or a keyboard, the allocation of memory between various applications, and the prioritization of applications when multiple ones run concurrently. Each program which is installed on a desktop or a notebook functions by sending requests to the OS for various 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 field, the OS is what runs a server together with all of the software installed on it, which includes not only website scripts, but, in addition every other application such as a VOIP or a game server. When there're virtual machines created, they work with a guest OS that runs on the server host OS.
Multiple OS in VPS Hosting
In case you pick one of our virtual private server
plans, you will have 3 different Operating Systems to pick from - CentOS, Debian and Ubuntu. They are all Linux releases and we offer them instead of offering just a single OS, because the apps that you may want to run on the server could have specific requirements regarding the software environment. Each of the three has certain pros with regard to the available plans that you can later on install, but what is common between them is that they are really secure and dependable and have large communities that support them. The web hosting Control Panel alternatives for the VPS accounts depend on your Operating System choice, in order to provide you with more flexibility. In case you order the virtual server with one OS and you need a different one later, our tech support team can easily reinstall the VPS with the new one in a couple of minutes. We also offer you the option to keep the Operating System on your server up-to-date on a weekly basis.
