The largest BSD descendant — a complete operating system rather than a kernel plus a distribution.
That the base system is developed as one unit is the cultural difference from Linux: kernel, libc and userland live in the same tree and ship together. The ports system builds third-party software from source; pkg installs prebuilt binaries.
Technically known for ZFS, jails (containers long before Docker) and DTrace. Netflix Open Connect runs FreeBSD and serves a substantial share of the world's video traffic from it; the PlayStation system software is also FreeBSD-derived.
