The OSI physical (layer 1) layer's relationship<br>with the TCP/IP protocol model ( read as Transmission Control<br>Protocol/Internet Protocol Protocol ) is as much a mystery to me as it<br>seems to be to everyone else.<br><br> In Cisco CCNA we do mostly the OSI model and only a little of the<br>TCP/IP model. I have found your references to the lowest layer of the<br>TCP/IP model (network access ) only handling layer 2 equivalent of the<br>OSI which would only deepen the mystery (see<br><a href="http://www.tcpipguide.com/free/t_TCPIPArchitectureandtheTCPIPModel-2.htm" target="_blank">http://www.tcpipguide.com/free/t_TCPIPArchitectureandtheTCPIPModel-2.htm</a><br>)<br><br> I am wondering if the word model at the end of the KK statement had a<br>different purpose than the 4 layer TCP/IP model. Perhaps the intention<br>was to relate the physical layer of the OSI to the role of TCP ( layer 4<br>) and IP ( layer 3 ) layers still within the OSI model. Even then, I am<br>not sure there is a relationship between layer 1 and layers 3 and 4. The<br>layered model allows development and accelerates evolution, as the<br>fabulous slide show by John Bellavance outlines. Mark's slide show is<br>also very helpful in understanding the layers.<br><br>So, all in all I am in the same boat as you Russell.<br><br>Kevork Krozian<br>Edulists Creator Administrator<br><a href="http://www.edulists.com.au" target="_blank">www.edulists.com.au</a><br>tel: 0419 356 034<br><br><br>-----Original Message-----<br>From: <a href="mailto:sofdev-bounces@edulists.com.au">sofdev-bounces@edulists.com.au</a><br>[mailto:<a href="mailto:sofdev-bounces@edulists.com.au">sofdev-bounces@edulists.com.au</a>]<br>On Behalf Of Russell Quinn<br>Sent: Wednesday, 9 March 2011 1:44 PM<br>To: <a href="mailto:sofdev@edulists.com.au">sofdev@edulists.com.au</a><br>Subject: Re: [Year 12 SofDev] Physical Layer<br><br>Having read around a bit, I was under the impression that the TCP/IP did<br>not address the physical layer (as in pulse shaping, line voltages etc)<br>at all, and that it assumed the physical infrastructure was in place<br>ready to do the bidding of the TCP/IP protocol.
