What does multiple devices at once mean?

It means you can use more than one device at the same time, like playing with two toys instead of just one.

Imagine you have a toy robot that can move around and also has a light show. Normally, you might press one button to make it walk and another button to make it shine. But if your robot has "multiple devices at once," you can make it walk and shine all at the same time, no need to stop one action to start another.

Think of it like having two friends help you build a tower with blocks. One friend places the blocks, and the other stacks them up. Together, they work faster than just one person doing everything alone. That’s what "multiple devices at once" feels like, different parts of the device working together to do more things at the same time.

So next time you see something happen in two ways at once, it might be using multiple devices at once!
