Debian is a free, non-proprietary Linux-based operating system founded by Ian Murdock in 1993. Bundled with a secure, lightweight, but fully featured software suite, Debian is an ideal platform for general purpose computing.
An active development community, along with the general purpose software ecosystem and free license, make Debian a highly popular choice for running a web server.
Easy Package Management
Debian uses dpkg and APT for easy package management. The dpkg program provides easy-to-use command-line arguments for decompressing and installing Debian (.deb) executables. APT augments the package system with the apt-get program, which lets you install and uninstall programs from various repositories on the web and also provides some extra usability features. Both of these systems come pre-installed with Debian.
Pros and Cons
