What is BSD BSD stands for Berkeley Software Design Open source software program of AT&T UNIX Operating System. Ancestor of modern UNIX System V. Developed in 1976 by the University of California Started as User Program Develop as ARPANET from a project of the DARPA (Defense Advance Research Project Agency)

Why BSD is not popular BSD Programmers do not sell their codes BSD software system had no publishing capabilities The system developed is not easy to use compared to other systems They were sued by AT&T for using some of their codes. The case was settled in March 2000.

How is BSD Developed Programmers world wide develop codes to support the system. The contributors write codes and the codes must be verified by the committers. Committers are developers that have write access to source codes. There are core teams: FreeBSD and NetBSD that manages every project.

Software Releases FreeBSD, NetBSD, and OpenBSD provides 3 different releases The system development of versions is called “Current” FreeBSD assigns numbers to Current. Ex: FreeBSD 5.0-Current NetBSD uses different naming scheme. Ex: NetBSD 1.4.3G OpenBSD does not use numbers to name its products The release is usually done within the interval of 2 years The releases fix bugs using the SVN tree.

Available Versions FreeBSD – focus on high performance and easy to use NetBSD – runs from portable machines to large servers. Was once used on one of NASA missions OpenBSD – focus on security and data purity DragonFlyBSD – focus on high performance and scalability

BSD Features The applications are open source Provides high performance Provides reliability Provides quality of products and documentation Their license is more attractive Can execute most Linux binaries

Customer Service, Training, and Support Services, Training, and Support are provided by Each of the open source applications has a consultant (FreeBSD, NetBSD, OpenBSD)
