    ISO is an organization. OSI is a model.

    Edit: there are also definitely more than four “layers” (standard handoff points).

    • Physical involves the media and transmission format (e.g. EMF, waveform, etc)

    • data link involves multiplexing and addressing on the local segment

    • Network involves beyond-segment addressing

    • Transport involves standard endpoint communication methods (tcp/udp)

    Are you implying this is where everything ends?

    What about application level multiplexing (sockets)?
