What is the difference between a first-level, second-level and third-level domain name?

The easiest way to explain this is with an example: lea.verou.me.
– First-level domain (TLD): .ME – the domain extension.
– Second-level domain (SLD): verou – the main part of the domain.
– Third-level domain (subdomain): lea – a subdivision of the second-level domain.
For instance, if Lea registered verou.me, she could create subdomains like hersister.verou.me, which would be a different third-level domain than lea.verou.me.
