关于FreeBSD 7.0 Beta 1.5及下载

FreeBSD是一种类Unix操作系统，是由经过BSD、386BSD和4.4BSD发展而来的 Unix 的一个重要分支。

FreeBSD 是以一个完善的作业系统的定位来做开发。其核心、驱动程式以及所有的使用者层（Userland）应用程式（比方说是Shell）均由同一原始码版本控制系统保存（目前使用 CVS）。相较于另一知名的的作业系统Linux，其核心为一组开发人员设计，而使用者应用程式则交由他人开发（例如 GNU计划），最后再由其他团体整合并包装成Linux套件。

作为一个作业系统，FreeBSD 被认为相当地稳建可靠。在 Netcraft 的开机时间报告中，最长的开机时间前50名，最多使用的作业系统就是 FreeBSD（在某些作业系统中，像是一些特殊版本的 Linux，开机时间无法被计算）。长的开机时间可以表示FreeBSD的系统相当稳定，不用为了安装新版本的核心而重开机造成重新计算开机时间。

About FreeBSD

What is FreeBSD?

FreeBSD is an advanced operating system for x86 compatible (including Pentium® and Athlon™), amd64 compatible (including Opteron™, Athlon™64, and EM64T), ARM, IA-64, PC-98 and UltraSPARC® architectures. It is derived from BSD, the version of UNIX® developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.

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.
