Web Browser

The essential client software (Chrome, Firefox, Safari) that retrieves documents from a server via HTTP/HTTPS, then renders HTML, CSS, and JavaScript into a functional user interface.

A web browser is the core application for accessing the World Wide Web. It functions as a user agent, initiating requests for resources (like HTML files or images) from web servers using protocols such as HTTP and HTTPS. Upon receipt, the browser’s rendering engine interprets the code (HTML for structure, CSS for style, JavaScript for interactivity) to construct the visual page. Early browsers like Mosaic (1993) and Netscape Navigator (1994) established the paradigm; today, market leaders like Google Chrome, Mozilla Firefox, and Apple Safari drive modern web standards compliance and performance, ensuring a consistent user experience across the internet’s estimated 1.2 billion websites.
