What is a Browser?

A browser, or web browser, is a software application used to access and view websites on the internet. It interprets HTML code, including text, images, hyperlinks, and other web page elements, and displays the page on your device.

History of Browser

The history of web browsers is a fascinating journey that began in the early 1990s. The first widely used web browser was NCSA Mosaic, released in 1993, which played a crucial role in popularizing the World Wide Web. It was followed by browsers like Netscape Navigator, Internet Explorer, and later, more modern browsers like Firefox, Google Chrome, and Safari.

  3. Mobile Browsers: Designed for smartphones and tablets, optimized for small screens and touch interactions (e.g., Safari on iOS, Chrome on Android).
