Debian is a Linux release, that's widely used for desktop computers, but it's been gaining in popularity as a server Operating System during the last couple of years as well. It's really stable and protected, due to the fact that fixes are released within a few days after a problem is discovered. Debian has a vast support community, so when you have any kind of questions or troubles with the OS or with any of the 30,000+ packages it features, you'll be able to contact the developers immediately through e-mail using special e-mail lists and receive a reply in just 15-20 minutes. The Debian community offers the best level of support possible, since your questions will be handled by the same people who made Debian in the first place, so they have an exhaustive knowledge of how their system operates. As the Operating System is free to use and distribute, no license charges will be included with your website hosting fees and you'll be able to change the code files and any additional software which you install with no restrictions, to optimize the software environment for your Internet sites. What's more, Debian performs very well on any hardware, as it is light and efficient and doesn't need much memory.
