Different explanations for TCP Model

As I go through the OSI and TCP models, I can't seem to find a stable explanation of the TCP model. Some list the model as a 4 layer, some 5. Some call the 2nd layer Internet, some Network. Some call Layer 1 Network Access, some Physical. About the only common things I have found is that the top layer is called Application and the next layer is called Transport.

Is there a reference somewhere that lists what the TCP model that I need to know is?

Thanks!

    The good thing about learning TCP, the OSI model, memorizing those common 100 or so services to ports, is it's the exact same model, theory and even ports as has been for the past 30 or so years. So as obscure and arbitrary as it might all seem, once you get it all down it doesn't change much at all. Even IPv6 has been the "new thing" for like 15 years now.
