How does the internet work?

You ask: How internet work?

Imagine every cave connect to every cave with string. Caveman want send cave painting to friend far away. Internet chop painting into many tiny pieces. Each piece get address, like 'cave 42 by big river'. Pieces run through strings, hop cave to cave, sometimes take different paths. Friend's cave glue pieces back in right order. All happen faster than blink. Websites just paintings kept in big cold caves called servers, waiting for someone to ask. Cave wisdom: internet not cloud in sky. Internet is many strings and many caves working together.
