FreeBSD - это современная операционная система для компьютеров, совместимых с архитектурами x86 (в том числе Pentium® и Athlon™), amd64 (включая Opteron™, Athlon 64 и EM64T), Alpha/AXP, IA-64, PC-98 и UltraSPARC®. Она основана на BSD, версии UNIX®, созданной в Калифорнийском Университете в Беркли. Она разрабатывается и поддерживается большой командой разработчиков.

==============================

The FreeBSD developers are as concerned about security as they are about performance and stability. FreeBSD includes kernel support for stateful IP firewalling, as well as other services, such as IP proxy gateways, access control lists, mandatory access control, jail-based virtual hosting, and cryptographically protected storage. These features can be used to support highly secure hosting of mutually untrusting customers or consumers, the strong partitioning of network segments, and the construction of secure pipelines for information scrubbing and information flow control.

FreeBSD also includes support for encryption software, secure shells, Kerberos authentication, "virtual servers" created using jails, chroot-ing services to restrict application access to the file system, Secure RPC facilities, and access lists for services that support TCP wrappers.

Cutting edge features
FreeBSD offers advanced networking, performance, security and compatibility features today which are still missing in other operating systems, even some of the best commercial ones.

Powerful Internet solutions
FreeBSD makes an ideal Internet or Intranet server. It provides robust network services under the heaviest loads and uses memory efficiently to maintain good response times for thousands of simultaneous user processes.

Run a huge number of applications
The quality of FreeBSD combined with today's low-cost, high-speed PC hardware makes FreeBSD a very economical alternative to commercial UNIX® workstations. It is well-suited for a great number of both desktop and server applications.

Easy to install
FreeBSD can be installed from a variety of media including CD-ROM, DVD-ROM, floppy disk, magnetic tape, an MS-DOS® partition, or if you have a network connection, you can install it directly over anonymous FTP or NFS. All you need are these directions.

FreeBSD is free
While you might expect an operating system with these features to sell for a high price, FreeBSD is available free of charge and comes with full source code. If you would like to purchase or download a copy to try out, more information is available.

Contributing to FreeBSD
It is easy to contribute to FreeBSD. All you need to do is find a part of FreeBSD which you think could be improved and make those changes (carefully and cleanly) and submit that back to the Project by means of send-pr or a committer, if you know one. This could be anything from documentation to artwork to source code. See the Contributing to FreeBSD article for more information.
Even if you are not a programmer, there are other ways to contribute to FreeBSD. The FreeBSD Foundation is a non-profit organization for which direct contributions are fully tax deductible.
