You open your browser, type in a website address like www.example.com, and within seconds, a page appears. But what happens behind the scenes? Let’s break it down step-by-step:
1. DNS Resolution
The browser first needs to know the website’s IP address. It contacts a Domain Name System (DNS) server to translate the name www.example.com into something like 192.0.2.1.
2. Connecting to the Server
Once the IP is known, the browser sends a request to the web server hosting that website using a protocol like HTTP or HTTPS.
3. Sending the HTTP Request
The browser sends an HTTP GET request saying, “Please send me the homepage of this site.”
4. Server Responds
The server receives the request, processes it, and sends back the HTML, CSS, images, and scripts needed to build the page.
5. Rendering the Page
Your browser reads the code, loads resources, and displays the web page exactly how it was designed.
✅ In short: From DNS lookup to server response, your browser performs a complex chain of tasks in milliseconds—all to bring a website to your screen.
