Subject: STDIN, OUT, ERR and $stdin, out, err - Differences?

Can anyone explain what's happening here?

print $stdin.fileno  => 0
print $stdout.fileno => 0
print $sterr.fileno  => 0

print STDIN.fileno  => 0
print STDOUT.fileno => 1
print STDERR.fileno => 2

print STDOUT.object_id     => 21673330
print $stdout.object_id    => 21673330

I get the same results in and out of eclipse and with irb

ruby 1.8.6, XP

Many thanks.
