AMD64 and Intel EM64T based PC hardware (amd64), Intel,
AMD, Cyrix or NexGen <span xmlns="http://www.w3.org/1999/xhtml" class="quote">&#8220;<span class="quote">x86</span>&#8221;</span> based PC hardware
(i386), Intel Itanium Processor based computers

(pc98), and <span xmlns="http://www.w3.org/1999/xhtml" class="trademark">UltraSPARC</span>® machines (sparc64).
Versions for the <span xmlns="http://www.w3.org/1999/xhtml" class="trademark">ARM</span>® (arm), <span xmlns="http://www.w3.org/1999/xhtml" class="trademark">MIPS</span>® (mips), and
<span xmlns="http://www.w3.org/1999/xhtml" class="trademark">PowerPC</span>® (powerpc) architectures are currently under
development as well. FreeBSD works with a wide variety of
peripherals and configurations and can be used for everything
from software development to games to Internet Service
Provision. </p><p xmlns="http://www.w3.org/TR/xhtml1/transitional">This release of FreeBSD contains everything you need to run
such a system, including full source code for the kernel and
all utilities in the base distribution. With the source
distribution installed, you can literally recompile the entire
system from scratch with one command, making it ideal for
students, researchers, or users who simply want to see how it
all works. </p><p xmlns="http://www.w3.org/TR/xhtml1/transitional">A large collection of third-party ported software (the
<span xmlns="http://www.w3.org/1999/xhtml" class="quote">&#8220;<span class="quote">Ports Collection</span>&#8221;</span>) is also provided to make it
easy to obtain and install all your favorite traditional
<span xmlns="http://www.w3.org/1999/xhtml" class="trademark">UNIX</span>® utilities for FreeBSD. Each <span xmlns="http://www.w3.org/1999/xhtml" class="quote">&#8220;<span class="quote">port</span>&#8221;</span> consists
of a set of scripts to retrieve, configure, build, and install
a piece of software, with a single command. Over
24,000 ports, from editors to programming languages to
graphical applications, make FreeBSD a powerful and comprehensive
operating environment that extends far beyond what's provided
by many commercial versions of <span xmlns="http://www.w3.org/1999/xhtml" class="trademark">UNIX</span>®. Most ports are also
available as pre-compiled <span xmlns="http://www.w3.org/1999/xhtml" class="quote">&#8220;<span class="quote">packages</span>&#8221;</span>, which can
be quickly installed from the installation program. </p></div><div class="sect2"><div xmlns="" class="titlepage"><div><div><h3 xmlns="http://www.w3.org/1999/xhtml" class="title"><a id="idp61860336"></a>1.2. Target Audience</h3></div></div></div><p xmlns="http://www.w3.org/TR/xhtml1/transitional">This release of FreeBSD is

convenient way to obtain FreeBSD for new installations, as it
provides a convenient way to quickly reinstall the system if
necessary. Some distributions include some of the optional,
