Debian is a Linux release, which is widely used for desktop computers, but it has been gaining popularity as a server OS over the last few years too. It is very stable and secure, since fixes are released in just a couple of days after an issue is discovered. Debian has a large support community, so when you have any questions or issues with the OS or with some of the 30,000+ packages it includes, you are able to contact the developers right away through e-mail using special e-mail lists and receive a response within 15-20 minutes. The Debian community offers the best level of support possible, since all of your questions will be handled by the very same people who made Debian in the first place, so they have an in-depth knowledge of how their system operates. Since the Operating System is absolutely free to use and distribute, no license charges will be included with your hosting fees and you will be able to modify 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 really well on any kind of hardware, because it is light and effective and doesn't need much memory.
