Wikipedia is a free online encyclopedia, created and edited by volunteers around the world and hosted by the Wikimedia Foundation.

A uniform resource locator (URL), colloquially known as an address on the Web, [6] is a reference to a resource that specifies its location on a computer network and a mechanism for retrieving it.

English Wikipedia's URLs begin https://en.wikipedia.org/. That address on its own is redirected to the Main Page. The page name may include a namespace prefix (such as "Help:" in this page).

Wikipedia is written by volunteer editors and hosted by the Wikimedia Foundation, a non-profit organization that also hosts a range of other volunteer projects:
