FreeBSD是类UNIX操作系统，它基于加州伯克利大学的“4.4BSD-Lite”发行并带有一些“4.4BSD-Lite2”增强，面向i386、amd64、IA-64、arm、MIPS、powerpc、ppc64、PC-98、UltraSPARC等平台。它还间接地基于“386BSD”，此乃William Jolitz对加州伯克利大学的“Net/2”往i386系统上的移植，尽管如今只有极少的代码保留下来。FreeBSD被全世界的公司、因特网服务提供商、科研人员、计算机专家、学生、家庭用户等用于他们的工作、教育、娱乐中。FreeBSD带有20000多个软件包，它们是预编译和打包好了、便于安装的软件，并覆盖了广阔的应用领域：服务器软件、数据库和网页服务器、桌面软件、游戏、网络浏览器和商务软件，而这一切都是免费和易于安装的。
