What is a Wiki? Definition from Wikipedia:
A wiki is a type of website that lets anyone create and edit its pages.
Wikiwiki is a word from Hawaiian, meaning "fast" or "speed".
Every wiki can be changed, or edited by everyone, although some important pages cannot be changed by anyone. Wikis are central places where we all can share information with each other,
people can add new information, and then people read them.
Wikis allow information from all around the world to be collection.
