Artificial intelligence means that a computer can do some tasks in a way that seems a little bit like thinking.
For example, it can learn from many examples. If you show a computer many pictures of cats, it can later recognize whether a new picture also shows a cat.
The computer does not have real feelings and it does not understand the world like a human. It only follows the patterns it has learned from the examples.
Artificial intelligence already helps in many areas today. It can write texts, understand speech, recognize images or suggest useful information.
You can imagine it like practicing. The computer gets many exercises and becomes better and better at solving certain tasks.
Artificial intelligence is therefore a computer program that can learn from examples and perform tasks that are often done by humans.
