Web Browser
A Web Browser, often referred to simply as a browser, is a software application used to access, retrieve, present, and traverse information resources on the World Wide Web. Here's an in-depth look at web browsers:
History
- Early Development: The concept of browsing the web was introduced with the creation of the World Wide Web by Tim Berners-Lee in 1989. The first browser, called WorldWideWeb, was also developed by Berners-Lee and released in 1991.
- Expansion: The popularity of browsers increased with the release of Mosaic in 1993, which introduced graphical user interfaces, making the web more accessible to the general public.
