Default installed deamon's?

Hi experts,
I haved checked dir /etc/xinetd.d and there are no ftp and telnet files
in this dir
It means that the deamon's for ftp and telnet has not been installed on
my server or OS.
But,my question is in the same folder /etc/xinetd.d i have got files like:
echo netstat ....

so, How the netstat file is present there??? Is the netstat deamon or server has installed?? IF YES,then IS it installed by default or it needed
some CD to get install???

Thanks for any HELP!!
