Technology explained simply, with animations

You use dozens of technologies every day without seeing inside them: the phone that finds your location, the Wi-Fi that carries a video across the room, the password that's never stored as plain text, the search engine that ranks billions of pages in a fraction of a second. Know.it's technology lessons open those black boxes. Each animated lesson traces what happens step by step — packets hopping between routers, bits flipping in a chip, signals bouncing off satellites.

Browse free explainers covering the internet and networking, computers and programming languages like Python and JavaScript, cybersecurity and encryption, everyday devices such as touchscreens, microwaves and electric cars, and newer ideas like cloud computing, blockchain and 5G. Every card links to a short written answer in plain English. Visual lessons can be requested using available credits or plan allowance.

No technical background is needed — lessons start from what you already know and build up. Ask about any gadget or piece of software you're curious about, and hear the explanation in English, Hindi, Marathi, Tamil, Telugu, Hinglish and Minglish, depending on your plan and selected lesson options.
