An open-source Unix-like operating system derived from Berkeley Software Distribution (BSD). It emphasizes security, performance, and advanced networking capabilities.
Compound of 'free' (as in freedom and cost) and 'BSD' (Berkeley Software Distribution). BSD originated at UC Berkeley in the 1970s-80s as enhancements to AT&T Unix, with FreeBSD emerging in 1993 as a freely redistributable version.
FreeBSD powers much of the internet infrastructure invisibly - Netflix, WhatsApp, and many major websites run on it because of its legendary stability and performance. Despite being less famous than Linux, FreeBSD's code has influenced everything from macOS (which shares BSD heritage) to PlayStation operating systems!
