What is DNS?
The internet's phone book that translates domain names into the server addresses computers understand
Why It Matters
DNS ensures users can find your website using your domain name instead of memorising numbers
Real-World Example
When you type 'google.com', DNS looks up and connects you to Google's actual server address
“Understanding terms like DNS matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
From definition to deployment
Knowing the term is step one. Using it in something real is the rest.
