[Year 12 SofDev] SD key knowledge

[David Dawson]

My guess is that it means the 'physical layer' relates to 'network
standards' in Hardware, like the electronics and microtechnology in
modems and network cards, SIMS etc; connections like CAT 5 and 802.11
wireless transmission - which then must send packets via a standard
communication protocol (TCP/IP) for transmission of data across the
Internet and LANs.
Hence this relationship points to a universal standard for Internet
connection devices.
Let me know if I am warm .....

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).

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?
