You know how sometimes you watch a show or movie on a DVD, and you really like it and want to watch it over and over again? Well, a DVD ripper is a special computer program that helps you make a copy of that movie or show so you can easily watch it on your computer or other devices without needing to use the DVD player.
Think of it like this - when you draw a picture on a piece of paper, the paper is the original and the picture is a copy, right? That's just what a DVD ripper does - it takes the original movie or show on the DVD and makes a copy of it so you can watch it whenever you want without needing the DVD.
But there are some rules to follow when using a DVD ripper, even though it's a helpful tool. You should only make copies of DVDs that you own, and not share those copies with other people without permission. It's like sharing toys - you wouldn't want someone to take your favorite toy without asking, right?
So, a DVD ripper helps you make copies of your favorite movies and shows from DVDs so you can watch them easily, but you need to follow rules and only use it with DVDs that you own.
