Synchronization is when two or more things work together at the same time. Just like how you and your friend might start clapping at the same time or how a choir sings the same song together. In technology, synchronization happens when different devices or programs communicate with each other to make sure they are all doing the same thing at the same time.
For example, think about how you listen to music on your phone. If you start a song on your phone and then hit play on your smart speaker, you want the same song to be played at the same time on both devices. That's synchronization!
Another example could be when you and your mom are working on a puzzle together. You want to make sure you're both working on the same puzzle, that you're putting the pieces in the right spots, and that you're not trying to fit the same puzzle piece in at the same time. That's synchronization!
Overall, synchronization is about making sure different things are working together smoothly and without any confusion, just like when everyone sings the same song or when you and your friend high-five at the same time.
