Step-by-step explanation:
The last two parts of a host name are known as the top-level domain (TLD) and the fully qualified domain name (FQDN).
The TLD is the rightmost part of a domain name, commonly seen as .com, .edu, .org, etc. It represents the highest level in the domain name system hierarchy.
The FQDN is the complete domain name of a specific host, including the host name, domain name, and TLD. It is often used to specify the exact location of a resource on the internet.
