Subject: Usenet Mail Addresses

I am sure that I am not the only Arpa/Milnet user who doesn't fully understand
the structure of a Usenet address.  I recognize that the "!" indicates the
path between two hosts, but what does {decvax,unc,hao,cbosgd,seismo,aplvax,uci}
mean?  If anyone of those is the beginning of a path, how do we decided what
is the preferred route?
