  Every computers are built to understand numbers and as human we don’t need to keeps numbers in other to communicate with computer. Talking bout DOMAIN NAME SYSTEM What is DNS? Think of the Domain Name System (DNS) as the phonebook of the internet. When you want to visit a website—like www.google.com—you type the name into your web browser. But computers don’t use names to find websites; they use numbers, called IP addresses (like 142.250.64.78). That’s how one computer finds another on the internet. So, DNS is the system that translates the name you type (like google.com) into the actual IP address that your computer needs to find the website. Real-World Example Let’s say you want to call your friend “Emma.” You look up her name in your phone, and your phone knows Emma’s number and calls her. DNS works the same way: • You type www.example.com • DNS finds the correct IP address for that name • Your browser uses that IP to connect to the website
