Web Browser
A web browser is an application for retrieving and presenting information resources on the World Wide Web such as Google Chrome, Microsoft Edge, Safari, Opera, and Firefox. An information resource is identified by what we call the Uniform Resource Identifier (URL for brevity), a web page, image, video, or other content pieces. Tim Berners-Lee invented the first web browser in 1990, called WorldWideWeb (later renamed Nexus). Mosaic followed it in 1993, which Marc Andreesen innovated, and then followed by several more web browsers such as Internet Explorer, Opera, Mozilla, and Safari.
