OPEN SOURCE OPERATING SYSTEM FreeBSD has hit its 20th birthday. FreeBSD turned 20 on 19 June and it continues to run vital network infrastructure services.
FreeBSD introduced a number of innovations that have been adopted by some Linux distributions. In particular FreeBSD's Ports collection, which builds software from source code rather than pre-packaged binaries, was copied by Gentoo Linux with its portage system.
FreeBSD is also known for having one of the most robust internet networking stacks and is frequently used by researchers and industry as the basis for simulation and production systems.
