FreeBSD 技术

FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), a version of Unix developed at the University of California, Berkeley. The project began in 1993 as an outgrowth of 386BSD and released FreeBSD 1.0 later that year. It is developed as a complete operating system, with the kernel, device drivers, userland utilities, build system and documentation maintained in a single source tree.
