At Internet there is a tremendous amount of argument over which operating system is the best for web hosting. There are anti-windows haters, there are FreeBSD fanatics and more. But which is the best? The truth is it depends on what you are doing. The servers which run the web sites and the server software all run on a computer program known as the operating system. If you are running a personal computer chances are that you are running Windows ME, XP, NT or some other similiar computer program. That is the operating system of your computer. With web hosting servers they also need a operating system and there are essentially three different competing versions.
