Debian's attention to detail allows us to produce a high-quality, stable, and scalable distribution. Installations can be easily configured to serve many roles, from stripped-down firewalls to desktop scientific workstations to high-end network servers.
Debian is especially popular among advanced users because of its technical excellence and its deep commitment to the needs and expectations of the Linux community. Debian also introduced many features to Linux that are now commonplace.
Debian was the first Linux distribution to include a package management system for easy installation and removal of software. It was also the first Linux distribution that could be upgraded without requiring reinstallation.Debian continues to be a leader in Linux development. Its development process is an example of just how well the Open Source development model can work — even for very complex tasks such as building and maintaining a complete operating system.
