Wikipedia

Wikipedia is a free, multilingual online encyclopedia hosted by the Wikimedia Foundation, a nonprofit organization. It relies on a collaborative model where volunteers around the world write, edit, and maintain articles across nearly all fields of knowledge. Content is organized into separate language editions, each maintained by its own community of contributors and editors. The platform serves students, researchers, journalists, and general readers seeking quick access to reference information on virtually any topic. Its articles are licensed under open terms, allowing free reuse, redistribution, and modification of the content by anyone.
