How does the Domain Name System (DNS) works?

Over the years, I have written articles on Domain Name System (DNS) and how and why you should do certain things. I came across this DNS graphic this morning.

As you can see, a never-before-seen DNS request is sent to a resolver, then a root server, then a TLD server, then an authoritative server, and finally back to the client. All of this is done in milliseconds (ms). As old as DNS is, it still significantly impacts modern computer networks.
