FreeBSD's origin Tuesday, August 21 2001 3:15 PM FreeBSD is a UNIX system running freely in the Intel platform, which can be available free of charge on the Internet. It has an extremely excellent performance, making it recognized by computer researchers and network professionals. Therefore, not only the professionals use it as a UNIX workstation, many companies, especially ISP (Internet Service Providers), but also provide network services for their many users using servers running FreeBSD. In 1969, AT & T invented the UNIX operating system, and Unix did not use UNIX as its formal goods. Researchers were only used in the laboratory and perfect it. The source code of UNIX is also spread to colleges, which makes UNIX a wide range of popularization. At the University of California, Berkeley is quite much more improved in UNIX. Increases many advanced features, including better memory management, fast and robust file system, most of the original source code has been rereaded, to support These new features, and put their UNIX a complete UNIX system -BSD UNIX (Berkeley Software Distribution), released outward. BSD UNIX has considerable influence in the historical development of UNIX, which is adopted by many commercial manufacturers, making many commercial UNIX, and TCP / IP is the first TCP / IP in BSD UNIX, which is closely combined with Unix. After some historical copyright disputes, mutual promotion, BSD UNIX and UNIX SYSTEM V form two mainstreams of UNIX, and modern Unix versions are mostly the two versions of derivatives. 4.4BSD Lite is the foundation version of the modern BSD system. BSD UNIX uses a myth's elf image as a mascot, this mascot mark is used along each BSD release. December 1993 FreeBSD version 1.0 was officially released. Anyone can freely obtain the FreeBSD system by purchasing a CD or through the Internet download, so that FreeBSD has achieved great success. FreeBSD also supports the largest and busiest file server on the Internet - FTP.cdrom.com. Since the UNIX trademark belongs to the X / Open organization, FreeBSD is just a free operating system, and FreeBSD cannot be called Unix from the legal perspective (not using UNIX). However, based on the history of UNIX itself, FreeBSD can be the most juicy original Unix. Because FreeBSD is very concerned about the performance and stability of the system, the development of FreeBSD is very active and is very open. Therefore, in system development, it supports multiple versions of FreeBSD systems in parallel, some versions are used to provide a most stable operating system, and others have gradually integrated into a new feature, so that FreeBSD is constantly evolving.
