[SaF] external data bus vs. address bus vs.

[zeebo]

Okay, I am pretty sure I have the binary number system down and thanks for
those of you that helped with that! But now I need help with the external
data bus and address bus on the motherboard. I have a pretty good idea of
what both of them do but I don't really understand the "why's" and the
"how's". It is hard for me to explain what I need help with when I don't
really understand it myself. So if anyone knows where I might be able to get
help with this I would really appreciate it.

Thanks in advance,

Kim
