Demoware

Okay kiddo, have you ever gone to the store and saw a toy that was on display but you couldn't play with it? That's kinda like what demoware is.

Demoware is software that's made to show you what a program can do, but you can't use it forever. It's like a free trial that lets you see the cool features, but you can't keep using it after a certain amount of time.

Just like how you can't keep playing with the toy in the store forever, you can't keep using the demoware forever. But it can be a great way to learn about a new program before you buy it, just like how you can look at the toy in the store and decide if you want it before you buy it.
