How Data Travels

1. You type a URL in your browser
2. Your computer sends a request to a DNS server
3. DNS translates the domain to an IP address
4. Your request travels through routers to the server
5. The server sends back the webpage data
6. Your browser renders the page

Fun Fact: Data can travel around the world in milliseconds through undersea cables!
