No, in either case it's referring to the local machine.
If your domain is example.com, http://www.example.com/myFile.html would
also refer to the file /var/www/html/myFile.html. Here you're accessing
your machine through the web browser from an external source; if you
call http://localhost/myFile.html you're calling the web browser from
the same machine.
localhost always refers to the machine itself. It's the web browser
which is translating the directory.
And if you have the appropriate daemons running, you can
telnet localhost
ftp localhost
ping localhost
etc.
which does exactly the same things as
telnet example.com
ftp example.com
ping example.com
The only difference is the first ones you're calling from the local
machine; for the second group you're calling from either the same or a
different machine.
