Domain
A domain is your website’s human-friendly address, like kbcafe.com, that you rent and point at a server.
Think of it like
It’s the street address of your site. You don’t own the land forever; you register the address year by year.
Example
kbcafe.com is a domain. “.com” is the extension; the part before it is the name you chose.
Why it matters
A domain is usually the first thing you buy when starting anything online, and it ties together your site, email, and DNS.
