TCP/IP the contradiction...?

In TCP/IP four layer model, The second Layer is Network Layer Which consists of protocols Like IP,ICMP..Similarly the above Layer Transport Layer consists of protocols like TCP & UDP. My Q is

TCP is - Connection Oriented Protocol
But the Lower Layer
IP is - Connectionless Protocol.

How these two layers communicates & How actually communication is handled in Tcp/Ip model ?

Actually the second layer from the bottom is the Data Link layer not the Network Layer, that is the 3rd from the bottom. mmedwid has a good article there for understanding the model. If you are interested in really learning TCP/IP and OSI Modeling then stay with the Cisco based learning materials, they are far above the rest.

I did this from memory, so there are bound to be some minor errors in the above. Yes, the second layer is "data link" not "logical" .. I knew it didn't sound right when I wrote it, but I was talking on the phone while I typed :-D
