The kind of answers given below might not be very helpful.
An Internet "domain" only has meaning in the context of DNS
"zones".
You either have to understand this or trust somebody that does
understand it.
DNS is the Domain Name System of the currently existing public IP
Internet.
Unlike IP addresses, which are to a large extent physically
distributed all the way down to end user networks, DNS names are
a weak concept and can change easily.
DNS "zones" are "delegated".
The "root" zone (embodied on a few DNS server machines) has
delegated COM, NET, ORG, EDU, MIL, INT, ARPA, and all other "top
level domains" (TLDs) to various other server machines.  The
"root" servers are "authoritative" only by  convention and
agreement.  Someplace upstream of you, a DNS server machine
operator has a file with the IP addresses of the root servers.
If your operator changes those, then you have a totally different
worldview.  Everything could change.  COM might not exist any
more ...
When you register a COM subdomain, you or your network operator
has been "delegated" a zone.  In this case it's called a
second-level domain.  So if you have bubba.com, bubba is both a
zone and a domain.  It also happens to be a SUBdomain of COM.
If you want to try to sell SUBdomains under bubba.com, you can
try.  Those also will be zones or domains.  If somebody can
convince you to do this, you can DELEGATE little.bubba.com to
somebody.  They then completely control the "little" SUBdomain
under the "bubba" subdomain under COM.  All are zones, all are
domains.  They are all SUBdomains of something.  COM is a
subdomain of "root".

Internet "domains" only have existence and meaning in the context
of the DNS, which is only one of MANY services that run on the
public IP Internet.

There's absolutely NO DOUBT as to what an Internet domain name is
right now ...

If I wanted to, I could create some new naming service and
advertise it.  I could take registrations for names.  I could
even call them domains.  But that would not make them Internet
"domains".
