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. Wikipedia[c] is a free online encyclopedia written and maintained by a community of volunteers, known as wikipedians, through open collaboration and the wiki software mediawiki Founded by jimmy wales and larry sanger in 2001, wikipedia has been hosted since 2003 by the wikimedia foundation, an american nonprofit organization funded mainly by donations from readers 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). It was created by jimmy wales and larry sanger on 15 january 2001, as wikipedia's first edition.
By replacing en with the code for another language, you can reach the main page of the wikipedia in that language, if it exists For example, replacing mr in place of en will take you to the main page of marathi wikipedia. A shorter form, called a (relative) url, is used when a computer could correctly fill in the full (absolute) url from context For example, of /wiki/url only works for a link on wikipedia to this page on wikipedia. We use simple english words and grammar here The simple english wikipedia is for everyone, such as children and adults who are learning english
All of the pages are free to use. A url starting with www.wikipedia.org redirects to the corresponding one starting with en Only www.wikipedia.org itself leads to a portal page instead of the main page of the english wikipedia
