An internet encyclopedia is a special type of book that you can find on the computer. It's like a big library where you can look up and read about a bunch of different things.
Imagine you wanted to learn about whales. If you opened up an internet encyclopedia and searched for "whales", you would find a page all about them! There would be pictures, words, and sometimes even videos to help you learn all about whales, what they look like, and where they live.
The best part is that you can learn about a bunch of other things too! You could learn about math or geography or even animals that live in different countries. An internet encyclopedia is a really great way to learn about all sorts of things and it's super easy to use, just like looking through a really cool book!
