<i>SD U3O1 KK04<br>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</i><br><br>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.<br>
<br>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 <a href="http://www.vceit.com/slideshows/SD-OSI.ppt">slideshow</a>).<br>
<br>But the second part of KK04 really has me baffled: <i>the relationship of the physical layer to the Transmission Control Protocol/Internet Protocol model.</i><br>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.<br>
<br>Can someone suggest why the relationship between the OSI physical layer and TCP/IP is so significant? <br>Has this relationship been in the papers? Has this physical relationship resulted in offspring?<br>Is Mr OSI going to be on Oprah... or the Jerry Springer show?<br>
