DNS (Domain Name System) is like the internet’s phonebook.
When you type a website name (like google.com) into your browser, your computer doesn’t understand names—it needs an IP address (like 142.250.72.14) to connect. DNS translates the human-friendly domain name into the machine-friendly IP address so your browser can find the right server.
Without DNS, you’d have to remember numbers for every site instead of simple names.
