An "Internet Domain Name" or "Web Address" is
your unique identity address on the Internet. A domain name takes
the form of a string of characters, followed by a period or "dot" and
then by another string of characters, like .com, .net or .org.
The last set of characters is referred to as the Top Level Domain,
or "TLD". Your domain name is referred to technically
as a Second Level Domain, or "SLD".
