Portable Native Client (PNaCl)

Portable Native Client (PNaCl) is a technology developed by Google that allows developers to create high-performance web applications using native code, which is usually fast but hardware-specific. PNaCl compiles this code into a portable format that runs securely inside a web browser across different operating systems and devices. This ensures apps work consistently and efficiently without sacrificing security or requiring users to install additional software. Essentially, PNaCl enables the web to offer complex, fast-running applications similar to desktop software, with cross-platform compatibility and built-in safety.
