Remember when you learned to recognize a dog? At first, you might have thought that every animal with four legs is a dog. But then, maybe your parents told you that dogs have certain features, like a wagging tail, barking sound, or a certain face shape. Gradually, you got better at telling dogs apart from other animals.

A neural network is something similar, but for computers. It's a kind of system that helps computers learn from examples, just like you learned to recognize a dog. So if we show a computer lots of pictures of dogs and tell it "This is a dog," over time, the computer will learn to recognize dogs on its own. This is how a neural network works!
