Group-stack
Okay kiddo, let me explain what a group-stack is in a way that you can understand. Imagine you have a bunch of toys, and you want to put them away in your toy box. Now, you don't want all your toys mixed up in the box, you want them organized into groups. So, you decide to group your toys by type - all your cars together, all your dolls together, and so on.
Now, instead of just putting all your cars in one big pile, you want to stack them neatly on top of each other so that they don't take up too much space. This is like a group-stack, but instead of toys, we're talking about things like computer files or data.
Basically, a group-stack is a way to organize information into different categories or groups, and then stack those groups on top of each other in a neat and organized manner. This helps keep things easy to find and saves space, just like how stacking your toys neatly in your toy box makes it easier to find and doesn't take up as much room.
