SD U3O1 KK04
Purposes and functions of the physical layer (Layer 1) of the OSI and
the relationship of the physical layer to the Transmission Control
Protocol/Internet Protocol model

For quite some time now I've been avoiding this KK because I'd rather
clean a dead dog's ears than spend time on the OSI.

But in the end I had to find the cotton buds and get stuck in, and I
think I have a reasonable overview of the OSI and how TCP/IP maps to it.
(even produced a draft slideshow
<http://www.vceit.com/slideshows/SD-OSI.ppt> ).

But the second part of KK04 really has me baffled: the relationship of
the physical layer to the Transmission Control Protocol/Internet
Protocol model.
I know that TCP/IP's Network interface layer maps to OSI's physical
layer (and the data link layer), but for the life of me I can't see how
it's any more significant than any of OSI's or TCP/IP's other layers.

Can someone suggest why the relationship between the OSI physical layer
and TCP/IP is so significant?  
Has this relationship been in the papers?  Has this physical
relationship resulted in offspring?
Is Mr OSI going to be on Oprah... or the Jerry Springer show?
