4. Imagine that your six-year-old cousin asked you this question: "How can a cat video show

up on my tablet? Is it magic?" How would you explain the process of data transmission in
a way simple enough for a young child to understand?

Well, your tablet is like a special window into the world of the internet. When you tap on it, you can see all kinds of cool things, like cat videos! But how does the cat video get from the internet to your tablet?

It's kind of like sending a letter in the mail. When you want to send a letter, you write your message on a piece of paper, put it in an envelope, and send it through the mail. Then, the mail carrier takes it to the post office, where it gets sorted and sent to its destination.

In the same way, when you want to watch a cat video, your tablet sends a message to the internet asking for the video. The video is like a special letter that gets sent back to your tablet through the internet "mail." But instead of paper and envelopes, it's all done with special signals that travel through the air and wires.

So it's not really magic, it's just like sending a letter, but with signals and wires instead of paper and envelopes!
