What is Domain name

Domain name is an easy-to-remember address that can be translated by DNS
into server's IP address. Domain names are hierarchical. Domain's suffix
indicates which TLD (top level domain) it belongs to, for example .com,
.gov, .org, .net, or .jp. Recently ICANN (Internet Corporation for Assigned
Names and Numbers) added several new TLDs, like .biz, .pro., and .museum, etc.

Example: google.com amazon.com there are more simple than
202.145.222.22 (example)
