CNN (Convolutional Neural Network)

Friendly Description: A Convolutional Neural Network is a kind of AI that's especially good at understanding pictures. It works a bit like the way our eyes scan an image: starting with small details (edges, colors) and slowly building up to bigger ideas (a nose, a face, a person). This step-by-step approach is what makes it so powerful for visual tasks.

Example: When your phone automatically tags your friends in photos, a CNN is doing the work behind the scenes. It first picks up tiny features like eyes and curves, then combines them into faces, and then matches those faces against people you know, all in less time than it takes to blink.
