[newbie] Xwindows

[JK]

I have two machnes running on my network. one dual 200 192 megs of ram,
and a amd 450 with 64 megs of ram.

I log on to my amd machine, and I try to start up xprograms. I remember
my unix teacher showed us how to do it, a year ago. I forgot how to do
that now.

What do I need to do, to get xwindows programs to run on my terminal
from the remote machine?

Thank you
