What does the part after a domain mean?
The URL in the address bar in your browser is comprised of
several components. First is the protocol used to transfer the
files from the web server to your web browser (commonly HTTP or
HTTPS) next comes the domain name (which is itself comprised of
several parts), followed by the directory path to the specific web
page to be loaded. The part after the domain name might look like:
/path/to/web/page
The domain name is comprised of several parts. The first is the
top-level domain, for example .com, .net, .org, .us, etc. Next
comes the second-level domain name, in our example above this would
be "example" Second level-domain names come directly to the left of
the top-level domain (the .com, .net, etc.). You can have third
level-domains which come immediately to the left of a second level
domain (in our example the "www" is a third-level domain). You can
have fourth- and fifth-level domains and so on.
