Debian is a Linux release, that is preffered for desktop computers, yet it has been becoming more popular as a server Operating System over the last few years too. It's very stable and secure, because fixes are released in just a couple of days after a problem is discovered. Debian has a large support community, so if you have any questions or troubles with the OS or with some of the 30,000+ packages it is equipped with, you will be able to contact the developers without delay through e-mail using special e-mail lists and receive a reply in just 15-20 min. The Debian community provides the top level of support possible, since all of your questions will be handled by exactly the same people that built Debian in the first place, so they have an exhaustive knowledge of how their own system functions. Since the Operating System is 100% free to use and distribute, no license costs will be added to your website hosting fees and you will be able to change the program code files and any other software that you install without any restrictions, so as to optimize the software environment for your Internet sites. What's more, Debian performs very well on any hardware, because it is light and quick and doesn't need a lot of memory.
