**Native Client** is a sandbox for running compiled C and C++ code in the
browser efficiently and securely, independent of the user's operating system.
**Portable Native Client** extends that technology with
architecture independence, letting developers compile their code once to run
-in any website and on any architecture.
+in any website and on any architecture with ahead-of-time (AOT) translation.
In short, Native Client brings the **performance** and **low-level control**
of native code to modern web browsers, without sacrificing the **security** and
**portability** of the web. Watch the video below for an overview of
Native Client, including its goals, how it works, and how

+Two Types of Modules
+====================
+
+Native Client comes in two flavors.
+
+* **Portable Native Client (PNaCl)**: Pronounced 'pinnacle', PNaCl runs single,
+ portable (**pexe**) 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.
+* **Native Client (NaCl)**: Also called traditional or non-portable Native
+ Client, NaCl runs architecture-dependent (**nexe**) 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 `Chrome Web Store (CWS)
+ <https://chrome.google.com/webstore/category/apps>`_. Fortunately, work from
+ PNaCl modules can be used to create NaCl modules.
+
+These flavors are described in more depth in :doc:`PNaCl and NaCl
