Debian is a Linux release, that is preffered for desktop machines, yet it's been becoming more popular as a server Operating System over the last couple of years as well. It is very dependable and protected, as fixes are released in a few days after an issue is discovered. Debian has a huge support community, so when you have any kind of questions or problems with the OS or with some of the 30,000+ packages it includes, you can contact the developers right away via e-mail using special mailing lists and receive a reply within 15-20 minutes. The Debian community offers the top level of support possible, as all your questions will be handled by exactly the same people who created Debian in the first place, so they have an exhaustive knowledge of how their own system works. Since the Operating System is absolutely free to use and distribute, no license costs will be included with your hosting fees and you'll be able to change the program code files and any additional software which you install without any restrictions, to optimize the software environment for your Internet sites. What's more, Debian performs really well on any hardware, as it is light and quick and does not need a lot of memory.
