<div class="big-intro"><p><strong>Native Client</strong> is a sandbox for running compiled C and C++ code in the
browser efficiently and securely, independent of the user’s operating system.
<strong>Portable Native Client</strong> extends that technology with
architecture independence, letting developers compile their code once to run
-in any website and on any architecture.</p>
+in any website and on any architecture with ahead-of-time (AOT) translation.</p>
<p>In short, Native Client brings the <strong>performance</strong> and <strong>low-level control</strong>
of native code to modern web browsers, without sacrificing the <strong>security</strong> and
<strong>portability</strong> of the web. Watch the video below for an overview of
Native Client, including its goals, how it works, and how
Portable Native Client lets developers run native compiled code on the web.</p>
+<aside class="note">
+This site uses several examples of Native Client. For the best experience,
+consider downloading the <a class="reference external" href="http://www.google.com/chrome/">latest version of Chrome</a>. When you come back, be sure to <a class="reference external" href="https://gonativeclient.appspot.com/demo">check out

+<div class="big-intro"><h2 id="two-types-of-modules">Two Types of Modules</h2>
+<p>Native Client comes in two flavors.</p>
+<ul class="small-gap">
+<li><strong>Portable Native Client (PNaCl)</strong>: Pronounced ‘pinnacle’, PNaCl runs single,
+portable (<strong>pexe</strong>) executables and is available in most implementations of
+Chrome. A translator built into Chrome translates the pexe into native code
+for the client hardware. The entire module is translated before any code is
+executed rather than as the code is executed. PNaCl modules can be hosted from
+any web server.</li>
+<li><strong>Native Client (NaCl)</strong>: Also called traditional or non-portable Native
+Client, NaCl runs architecture-dependent (<strong>nexe</strong>) modules, which are
+packaged into an application. At runtime, the browser decides which nexe to
+load based on the architecture of the client machine. NaCl modules must be run
+from the <a class="reference external" href="https://chrome.google.com/webstore/category/apps">Chrome Web Store (CWS)</a>. Fortunately, work from
+PNaCl modules can be used to create NaCl modules.</li>
+</ul>
+<p>These flavors are described in more depth in <a class="reference internal" href="/native-client/nacl-and-pnacl.html"><em>PNaCl and NaCl</em></a></p>
