Wiki

A wiki is like a super-powered website where lots of people can write and change things together. Think of it like a giant online book that anyone can help build! The first one was called WikiWikiWeb, and 'wiki' is a Hawaiian word that means 'quick'. So, wikis are all about sharing information fast!

A long time ago, a clever person named Ward Cunningham invented the very first wiki. He wanted a super simple way for people to share ideas online. He called it WikiWikiWeb because it was so quick to use. It was like building a website with building blocks that everyone could add to.

Wikis are amazing because they let everyone share what they know. Imagine a giant playground where everyone adds their favorite games. That's what a wiki does for information! It helps create huge collections of knowledge, like the famous Wikipedia, which is like the biggest library ever!

Wikis use special computer programs called 'wiki engines'. These engines let people easily add or change pages right from their web browser. It's like having a magic pen that lets you edit anything you see on the screen. Some wikis are open for everyone, and others are just for certain groups.
