PNaCl (Portable Native Client)

Portable Native Client (PNaCl) is a technology developed by Google that allows developers to run native code securely in web browsers. It enables applications written in languages like C or C++ to execute on various platforms without modification, ensuring consistent performance and security. PNaCl packages the native code in a format called "native client," which is then run in a sandboxed environment, preventing harmful actions. This means users can experience powerful applications directly in their browsers, similar to how traditional software works, without needing to install additional software or worry about security risks.
