Debian is a Linux release, that is widespread for desktop computers, yet it has been gaining popularity as a server Operating System during the last few years too. It's very stable and protected, due to the fact that fixes are released in just a couple of days after a problem is discovered. Debian has a large support community, so when you have any kind of questions or troubles with the OS or with some of the 30,000+ packages it comes with, you can easily contact the developers right away through electronic mail using special mailing lists and receive a response in just 15-20 minutes. The Debian community gives you the best level of support possible, as all your questions will be handled by exactly the same people that created Debian in the first place, so they have a detailed knowledge of how their system works. As the Operating System is absolutely free to use and distribute, no license costs will be added to your website hosting fees and you'll be able to modify the program code files and any additional software that you install without any restrictions, so as to optimize the software environment for your Internet sites. In addition, Debian performs very well on any kind of hardware, as it's light and efficient and doesn't need much memory.
