Also known as: World Wide Web, WWW, The Web
Global information system of interlinked hypertext resources accessed via the Internet using browsers and web protocols.
DESCRIPTION
The World Wide Web is a hypermedia system enabling documents and APIs to be identified by URLs and transferred using HTTP. It relies on open standards for content (HTML, CSS, JavaScript) and protocols defined by IETF and W3C. Web browsers render documents and execute client-side code, while servers deliver resources and data. The Web supports interactive applications, RESTful services, and data exchange formats. Its architecture emphasizes links, identifiers, and representation, enabling interoperability at Internet scale. Originating at CERN, the Web evolved from static pages to dynamic, app-like experiences.

TOP QUESTIONS
What is the difference between the WWW and the Internet?
The Internet is the global network infrastructure, while the Web is an information system built on top using HTTP, HTML, and URLs.
Category: Misunderstanding
When was the World Wide Web invented?
It was invented in 1989 at CERN by Tim Berners-Lee and released publicly in 1991.
Category: Origin
Which core technologies enable the WWW?
HTTP for communication, HTML for content structure, URLs for addressing, and browsers for rendering.
Category: Overview
How did the WWW transform data access?
It democratized information through hyperlinks and standard protocols, enabling mass content publishing and discovery.
Category: Impact
What is a common mistake about the WWW?
Confusing the Web with specific social platforms; the Web is broader and platform-agnostic.
Category: Mistakes
Is the WWW still relevant with apps and APIs?
Yes. Web standards underpin APIs, web apps, and content delivery across devices.
Category: Relevancy
What role does W3C play in the WWW?
W3C develops standards ensuring interoperability, accessibility, and security for the Web.
Category: Governance
What’s a historical alternative to the WWW?
Gopher provided hierarchical menu-based information retrieval before the Web’s widespread adoption.
