Debian is a preferred Linux distribution, which is used primarily on personal computers, however lots of people have begun using it lately as a web server OS as well, because of the stability and protection it provides. The latter is a result of the fact that Debian is developed and supported by countless qualified volunteers worldwide, which means that any patch that is required to fix a certain issue is released in a matter of days. The same community will also help with any question or problem that a user may ever have, since they can be contacted through electronic mail using mailing lists and a competent response will be sent in around 15-20 minutes. The advantage here is that your queries will be addressed by the same people who have developed the Operating System itself and they have a detailed knowledge of how it functions. As Debian is provided for free, you will not have to pay any license fees to use it and you will be able to customize it as much as you want or need. This is valid for the Operating System as well as the 30.000+ software packages that are available for it.
