A stream is like a magic river that carries things to you without stopping. Imagine your favorite cartoons or songs floating down this river, and you can pick them up whenever you want. This river never dries up and keeps bringing you new things all the time. Just like when you watch TV or listen to music on a tablet, the stream brings you what you want without waiting.
Think of it as a conveyor belt in a candy factory. The belt keeps moving and brings you candies one by one. You don’t have to wait for the candies to be made because they are already coming to you. This is how a stream works with videos and music; it keeps delivering them to you, so you can enjoy them right away.
Or imagine a mailbox that gets filled with letters every day. You don’t have to go to the post office to get your mail because the mailbox keeps getting new letters for you. A stream works the same way, bringing new shows, games, and songs right to your device, ready for you to enjoy anytime.
