Okay kiddo, let's talk about matter, which is a way for different smart devices to talk to each other. It's like a secret language they all understand so they can work together and do cool things.
Think of it like going to a new school and not being able to understand the other kids because they speak a different language. That's what it's like for smart devices, they all speak different languages and can't understand each other. But with matter, they can all speak the same language and understand each other!
So, let's say you have a smart light bulb and a smart speaker. Without matter, they wouldn't be able to communicate because they have different languages. But with matter, they can talk to each other and do things like turn the lights on and off when you ask your smart speaker to do it.
Matter is like a special code that all smart devices can understand. It's kind of like how animals have their own way of communicating with each other. For example, dogs bark to let other dogs know that they are there, and bees do a little dance to tell other bees where the flowers are.
Matter helps smart devices work together like a team, just like how you and your friends work together to play a game or build something cool. It's important because it makes everything easier and more fun!
