How does the internet work, and why do we need wi-fi to use it?
In: 0
Imagine the internet is like a huge library full of books. But instead of physical books, it’s full of digital information like videos, pictures, and websites. Just like in a library, you need a way to get to the information you want to access.
You don’t need wi-fi to access the internet, but you do on smart phones and in public places.
When you turn on your device’s wi-fi, it starts looking for a nearby signal. Once it finds one, it sends a message to the internet (like saying “hello” to a librarian) and the internet sends information back (like giving you a book to read). The wi-fi is the librarian giving you the things you’re asking for in the library. The library can exist without the librarian but then it’s just a a building with information inside it. Wi-fi is the way that data coems off the shelf and into your hands.
