What is a Web Browser?

A web browser is a software program that retrieves, interprets, and displays web pages and other online content, enabling users to browse and interact with the internet.

How do Web Browsers Work?

Web browsers use HTTP (Hypertext Transfer Protocol) to communicate with web servers and retrieve web pages. They interpret HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) to render web content.

  • Web Page Rendering: Browsers parse HTML and CSS to render web pages, displaying text, images, videos, and interactive elements in a visually appealing manner.
  • Tabbed Browsing: Tabbed browsing allows users to open multiple web pages within a single browser window, facilitating efficient multitasking and navigation.
  • Bookmarks and Favorites: Browsers offer the ability to save and organize frequently visited web pages as bookmarks or favorites, providing quick access to preferred sites.
  • Extensions and Add-ons: Browsers support extensions and add-ons that enhance functionality, such as ad blockers, password managers, language translators, and more.
