The History of Web Browsers
The concept of a web browser dates back to the early 1990s when the internet was still in its infancy. The first-ever web browser, named "WorldWideWeb" (later renamed Nexus), was created by Sir Tim Berners-Lee in 1990. This marked the beginning of a revolution in how humans interact with information.
Over the years, web browsers have evolved significantly. The introduction of Mosaic in 1993 made the internet more accessible to the general public. Later, Netscape Navigator dominated the market before Microsoft's Internet Explorer took over in the late 1990s. Today, browsers like Google Chrome, Mozilla Firefox, and Safari are leading the way with advanced features and performance.

It retrieves, presents, and navigates web pages, which are typically written in HTML, CSS, and JavaScript. By using a web browser, users can search for information, watch videos, shop online, and communicate with others across the globe.
Modern web browsers come equipped with features like bookmarks, tabs, extensions, and integrated search engines. These enhancements make browsing faster, more efficient, and more personalized for users.

How a Web Browser Works
When you enter a URL into your web browser, several processes occur behind the scenes:

2. DNS Lookup: It translates the domain name into an IP address using a DNS server.
3. Requesting Data: The browser sends an HTTP or HTTPS request to the web server hosting the website.
4. Rendering: Upon receiving the response, the browser parses the HTML, CSS, and JavaScript files to render the web page.
5. Displaying Content: Finally, the browser displays the content on your screen, making it accessible for interaction.
