FreeBSD (FBSD) is an advanced Unix-like operating system developed by the FreeBSD Project. FBSD is one of the most reliable, robust and secure operating systems in the world. It is free, open source and powers some of the internet’s largest web servers, including Yahoo’s and Sony’s (more companies). Rock-solid stability and the ability to perform extremely well under heavy workloads makes this operating system a popular choice among Internet Service Providers and Web hosting companies. A cohesive userland and kernel, the ports system and regular OS upgrades are the strengths of this OS.
FreeBSD is derived from the Berkeley Software Distribution (BSD), the version of UNIX developed at the University of California at Berkeley between 1975 and 1993. FreeBSD is not a UNIX clone. Historically and technically, it has greater rights than UNIX System V to be called UNIX. Legally, it may not be called UNIX, since UNIX is now a registered trade mark of The Open Group.
FreeBSD runs on Intel processors as well as on DEC Alpha, Sun UltraSPARC processors, Itanium (IA-64) and AMD64 processors and soon on Suns Niagara servers (FreeBSD 7).
FreeBSD is an operating system that is very flexible and can therefore be used for various purposes:
- FreeBSD – (web)servers
- FreeNAS – Network Attached Storage servers
- DragonFly BSD – Powering cluster computing
- PC-BSD and DesktopBSD – Desktop
- M0n0wall and pfSense – Firewall
- Frenzy – portable system administrator toolkit
- FreeSBIE and RoFreeSBIE- Live CDs
Stability, flexibility and security are what is needed for a good operating system, and FreeBSD has them all, whether you use it on your desktop or as server. There’s an interesting article on IBM’s website “Why FreeBSD” dealing with the strong points of FreeBSD.
