ELI5: Explain Like I'm 5

Wide area information server

A Wide Area Information Server is like a giant library where you can find lots of information about lots of things on the internet. Just like when you go to a library, you can search for a book or topic, and the librarian will give you the book or show you where to find it. With a Wide Area Information Server, you can search for things on the internet, like websites, pictures, videos and more. The server will find what you're looking for and show it to you, just like a librarian would. It's very helpful when you want to find something on the internet but you don't know where to look. Just like a library has a lot of books, a Wide Area Information Server has a lot of information, and you can access it from anywhere in the world!
