Okay, so you know how sometimes you want to find information about something, like how to bake cookies or what animals live in the ocean?
Well, there are special computer programs that help you find information called reference software.
Think of it like a really big, fancy library that has lots of books and magazines and even videos about all kinds of things.
When you use reference software, you can type in a word or phrase (like "chocolate chip cookies" or "sharks") and it will show you lots of different sources of information that can help you learn more about that thing.
It's like having a special helper who knows all kinds of stuff about everything!
