What is DNS and how does it work?

beginner

Re-explain

Answer: DNS translates human-readable domain names into IP addresses.
DNS Process:

User types www.example.com
Local DNS cache checked first
Query sent to recursive DNS server
If not cached, queries root name servers
Directed to TLD (.com) servers
Finally queries authoritative name servers
IP address returned to client
DNS Hierarchy: Root → TLD → Authoritative → Host
