The World Wide Web
The world wide web is a group of webpages which are connected to each other by links called hyperlinks.
A webpage is an electronic document that can be read/viewed by web browser software (e.g Chrome, Edge). Web pages are also know as Hypertext Documents which are written in Hypertext Markup Language (HTML).
Web pages are stored on Webservers, which can be accessed by a web address e.g. http://google.com.
Because many webservers can exist on the internet, the world wide web is a global interconnection of webpages via hyperlinks.
