What makes a smartphone so smart?
You tap a glass rectangle and it knows your face. You ask it a question out loud and it answers. You point it at a sign in another language and suddenly you can read it. How does a little slab of metal and glass do all that?
Inside your phone lives a chip smaller than your thumbnail called a processor — think of it as the phone's brain. This brain can do billions of calculations every single second. When you tap the screen, it instantly figures out where you tapped, what app you opened, and what should happen next. All before you can blink.
