Debian is a preferred Linux release, that's used mainly on personal computers, but numerous people have started using it lately as a web server Operating System too, because of the stability and protection it offers. The latter is a result of the fact that Debian is developed and supported by thousands of qualified volunteers around the globe, so that any patch which is required to fix a particular issue is released in a matter of days. The very same community can also help you with any question or issue that a user may ever experience, due to the fact that they can be contacted through electronic mail using e-mail lists and a qualified response will be sent in no more than 15-20 min. The advantage here is that all your questions will be addressed by the same people who have created the Operating System itself and they have an in-depth knowledge of how it functions. As Debian is provided for free, you won't have to pay any license fees to use it and you will be able to personalize 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.
