Web browser

A web browser retrieves resources from web servers, interprets formats such as HTML and CSS, and presents interactive pages through a graphical interface.

Hypertext Transfer Protocol: An application protocol for exchanging requests and responses between clients and web servers. Browsers use HTTP, usually its encrypted form, to request pages and related resources.
Uniform Resource Locator: A standardized address that identifies a resource and specifies how to locate it. Browsers use URLs to identify destinations and determine which resources to request.
WorldWideWeb: The first web browser and editor, created by Tim Berners-Lee at CERN in 1990. It combined browsing with editing, before browser use became centered on viewing pages.
Search engine: A service that indexes or otherwise organizes information and retrieves results in response to queries. Unlike a browser, it helps locate pages but does not itself render the web.
World Wide Web: A global information system of interlinked resources accessed over the internet. Browsers made this system practical to explore through linked pages and shared standards.
HTML: A markup language that structures the content of web pages. Browsers parse HTML into the document structure they display and expose to scripts.
Domain Name System: A distributed naming system that maps domain names to network information, including IP addresses. DNS helps browsers locate the servers named in web addresses.
Mosaic: A graphical web browser released by NCSA in 1993 that helped popularize the web. Its accessible graphical presentation helped bring browsers to a broad public.
Web crawler: Automated software that systematically visits web pages to discover or index content. Crawlers retrieve pages without providing the interactive browsing interface built for people.
Progressive web app: A web application built with browser technologies and enhanced with capabilities such as installation or offline use. It blurs the boundary between browser-based websites and installed software.
