On the local machine.
If I ftp to localhost and log in as 'gordon', I end up in my home
directory on the local machine. If I ftp to localhost and log in
as 'ralph', I end up in Ralph's home directory on the local machine.
If I http to localhost and request /, I get the web server's document
root directory (or an index file in it). If I ping localhost, I
get *no directory whatever*, I just get ping replies back. If I
log in on MySQL to localhost, I get the database I asked for, and
who cares what directory it's kept in (sometimes databases are
jumbled together in one large file, but if MySQL can figure it out,
that's fine with me) if I get the right one? If I connect an IRC
client to localhost, I end up talking to the IRC server on my local
machine (assuming one exists), and the directory is not relevant.

localhost refers to the local machine. The *whole* local machine.
Any directory is implied or specified by parts of the request other
than the hostname.
