Google Native Client

Google Native Client (NaCl) is a special technology that lets you run programs (like games or applications) directly in your web browser, without having to download or install anything extra. Think of it like playing a game on a tablet, but instead of downloading the game from an app store, you're playing the game right on a website.

The reason this technology is super cool is because it lets you do a bunch of things right in your web browser that you normally couldn't do. For example, NaCl can let you play games with full graphical capabilities that might have been too intensive for your web browser to handle before. It can also let you run applications that might have required you to download and install something separately on your computer.

How does NaCl work? Well, it's kind of like having a special mini-computer inside your web browser. When you open a NaCl program, your web browser creates a tiny, isolated space where the program can run safely, so it doesn't mess with anything else on your computer. This little computer is called a "sandbox".

One of the coolest things about NaCl is that it's super secure. Since NaCl programs run inside a sandbox, they can't "escape" and mess with other parts of your computer. This means it's very difficult for hackers or viruses to do anything bad to your computer through NaCl programs.

Overall, Google Native Client is a really neat technology that lets you do some pretty cool things right in your web browser without having to download anything extra or worry about security issues.
