What is scanner?

A scanner is like a robot that reads things and turns them into words on a screen.

Imagine you have a picture book, and instead of reading it with your eyes, you use a special tool that moves across the pages, like a finger tracing letters, and changes what it sees into text you can read on a computer or phone. That’s basically what a scanner does!

A scanner uses light to “see” what’s in front of it, just like how your eyes use light to see the world. When it moves across something, like a piece of paper or a photo, it captures tiny details and turns them into digital images.

Think about when you want to save a drawing or a note so you can look at it later on your tablet. A scanner helps you do that by turning the real thing into something digital, like magic, but without any real magic!
