Questions tagged [web]

Do not use this tag. For questions related to an aspect of the world wide web, use a more specific tag for it, such as [uri], [html], [http] or [w3c].

The World Wide Web (abbreviated as WWW or W3, and commonly known as "the Web") is a technology that connects various kinds of systems with interlinked hypertext documents accessed using networking protocols.

The credit of inventing the World Wide Web goes to many researchers, but it was Tim Berners-Lee also known as TimBL who not only proposed the idea of WWW (at CERN in 1989) but also gave his full contribution in development of 3 very significant technologies:

  1. Invention of URL (Universal Resource Locator) and URI (Universal Resource Identifier).
  2. HyperText Markup Language (HTML)
  3. HTTP (HyperText Transfer Protocol), a protocol for transferring HTML

The World Wide Web is an interconnected network which works as a bridge not only between two terminal ends (Web browser & Web server) but also to connect client machines to database servers with controlled access.

With a Web browser (client), one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks. The default port for requests and responses via HTTP protocol is port 80.

A web server, on other hand, receives the client's requests and generates the proper response for it. This includes an HTTP status code (like 200 Ok or 404 Not Found), a list of HTTP headers (which control things like response format and cookies), and the response body (like HTML content).
