The
domain name system has a hierarchical structure:
The
component furthest right to the domain name is called the Top
Level Domain. Top Level Domains are often country code, for
example .it (Italy), .be (Belgium), .nl (The Netherlands),
.... However there are also generic Top Level Domanis, for
example .COM, .NET and .ORG
The two
"newest" generic Top Level Domains are .INFO and .BIZ.
Other TLDs will be added soon.
The second
level domain is the component chosen by you, on the left of
the Top Level Domain. So Tuonome.it is a Second Level Domain.
To these
SLD's a domain
name holder can associate, by means of a number of technical
procedures, all the Internet services: WEB www.tuonome.it,
e-mail helpdesk@tuonome.it, FTP-service
and other.
