This flowchart shows how a user enters a domain name, how DNS finds the web host's IP address, and how the website files are sent back to the user’s browser.
Step-by-Step Trace - 6 Steps
Step 1: User types 'example.com' in the browser address bar.
Step 2: Browser sends 'example.com' to DNS server to find IP address.
Step 3: DNS server finds IP address 192.0.2.1 for 'example.com'.
Step 4: Browser connects to web host at IP 192.0.2.1.
Step 5: Web host sends website files to browser.
Step 6: Browser displays the website to the user.
