    hi, does anyone have a EASY way of remembering the OSI seven layer model and an explanation of each layer please?

    The easiest way I remember it is (Taken from a CBT Nugget video)!

    All people seem to need data processing!

    Application
    Presentation
    Session
    Transport
    Network
    Data
    Physical

    As for explanation... quick Google or I'm sure someone will have a little more time to explain (soz at work!) :)

    That is the way I learned the layers over 10 years ago.

    Th the OP as far as learning what happens at each layer and what protocols work in each layer I don't think there is a trick. That's just one of those things you have to study and explanations from multiple sources helps. watch the osi video at pro. messer, read the explanations at wikipedia and other places online.

    Some layers should be easier to learn than others such as layer 3 (network) that's where routing happens and you need an IP address for routing so the IP protocol is at layer 3. Layer one should be easy to remember that deals with the physical media and bits going across wires.

    Don't get stuck on it though. You need to have a good understanding for the rest of your studies but at the same time the rest of your studies will reinforce your understanding of the OSI model. For instance when you learn about TCP & UDP the transport layer of the OSI will become easier to remember.

    don't underestimate the importance of learning what kind of encapsulation happens at what layer and at what layers you have data (5,6,7) segments (4) packets (3) frames (2) and bits (1)

    cheers guys, as always great response!
    no doubt the AIO book explains in great length how to make the sausage pizza also :)

    Although I applaud your efforts, there are about the same number of spelling/grammar mistakes in your opening paragraph as there are in an entire MSPress book (i.e. lots).
    You might want to review that, I never read further and some other people might be put off for the same reasons.
