FreeBSD is a UNIX-like operating system for
the i386, amd64, IA-64, arm, MIPS, powerpc,
ppc64, PC-98 and UltraSPARC platforms based
on U.C. Berkeley's "4.4BSD-Lite" release, with
some "4.4BSD-Lite2" enhancements. It is also
based indirectly on William Jolitz's port of
U.C. Berkeley's "Net/2" to the i386, known as
"386BSD", though very little of the 386BSD code
remains. FreeBSD is used by companies, Internet
Service Providers, researchers, computer
professionals, students and home users all over
the world in their work, education and recreation.
FreeBSD comes with over 20,000 packages (pre-compiled
software that is bundled for easy installation),
covering a wide range of areas: from server software,
databases and web servers, to desktop software, games, web browsers
