Debian GNU/Linux or simply Debian is one of the oldest and in the meantime one of the most widely used operating systems in the world. This popularity is largely due to the fact that Debian is distributed as free open-source software under the GNU license. There are, however, other key advantages that have made it a top OS choice for millions of users worldwide. Debian is Unix-based and can be equally well used as a desktop and a server operating system, which makes it a multi-purpose solution for your machine, no matter whether you are a server administrator or just a regular user. Moreover, it can be very easily installed on your computer or server, despite the fact that its latest release, for example, includes more than twenty-six thousand software packages. Debian 7 is the latest in the long line of Debian distros. Although a lot of Debian based distros use the testing branch, stable Debians are very much that – stable. This has its advantages and disadvantages, as packages can sometimes get very out of date in the repositories. However, this does not effect security and bug fixes, and that’s what Debian 7.1 release is about.
