Linux vs. BSD

what's the difference?

Berkeley Software Division: FreeBSD- NetBSD- OpenBSD- DragonflyBSD

  • FreeBSD aims for high performance and ease of use by end users, and is a favourite of
    web content providers. It runs on a number of platforms, including i386 based systems
    (“PCs”), systems based on the AMD 64-bit processors, UltraSPARC® based systems, systems based on Compaq's Alpha
    processors and systems based around the NEC PC-98 specification. The FreeBSD project has
    significantly more users than the other projects.

  • NetBSD aims for maximum portability: “of course it runs NetBSD”. It runs
    on machines from palmtops to large servers, and has even been used on NASA space
    missions. It is a particularly good choice for running on old non-Intel hardware.

  • OpenBSD aims for security and code purity: it uses a combination of the open source
    concept and rigorous code reviews to create a system which is demonstrably correct,
    making it the choice of security-conscious organizations such as banks, stock exchanges
    and US Government departments. Like NetBSD, it runs on a number of platforms.

  • DragonFlyBSD aims for high performance and scalability under everything from a
    single-node UP system to a massively clustered system. DragonFlyBSD has several
    long-range technical goals, but focus lies on providing a SMP-capable infrastructure that
    is easy to understand, maintain and develop for.

There are also two additional BSD UNIX operating
systems which are not open source: XBSD/OS - Mac OSX
