Wikipedia is the world’s largest open, free, and collaborative online encyclopedia.
Launched in 2001 and supported by the Wikimedia Foundation, a US non-profit organization that works to share knowledge around the world, with over 35 million entries in more than 280 languages Wikipedia is one of the 10 most visited sites in the world .
Unlike traditional encyclopedias, the entries and definitions are written directly by users and not by experts. To ensure the accuracy of the information reported, Wikipedia is continuously reviewed by users, who can report and correct errors. Today it is considered an authoritative source.
From the possibility of being updated and corrected very quickly derives the name "wiki", which in Hawaiian means "very fast".
