    Well - for me having to remember OSI was *relatively* recent, and I use the mnemonic "All people seem to need data processing"

    Taking the initial letters as a cue "Application Presentation Session Transport Network Data-Link Physical".

    The IRQs and DMAs I admit are a problem. For DMA only one matters any longer - the floppy - all the rest are history.

    The IRQs, particularly those for the COM ports I always have trouble with!

    Learning by rote, unfortunately!

    There are certain 'tags' people use to remember the 7 layers of the OSI model.

    "All People Seem To Need Data Processing" (7-1)

    "Please Do Not Throw Sausage Pizzas Away" (1-7)

    "Pew! Dead Ninja Turtles Smell Particularly Awful" (1-7)

    None of which were invented by myself :)

    For DMA, IRQ and I/O Base numbers, I literally have them pinned on the wall by my PC desk. Whenever I glance away, they're there. And I gave similar lists to the guy I sit next to at work. Every so often he'll turn to me and go "What IRQ is the RTC?". I'll look stunned for a second, and then remember I asked him to pop quiz me :rolleyes:

    Unfortunately, that's all I have to suggest! Good luck :)

    To learn the IRQ's and DMA's I just wrote them down every day. First you have to look but then after a couple of days you get them off the top of your head.

    What course are you studying Clueless? OSI never popped up on my A+ course but the N+ is pretty much built on it!

    I'm glad you asked Deckard as Meyers barely touches on the OSI model so I haven't bothered revising it for my exam next week.

    What I did for the IRQs was this: on a little slip of paper write each IRQ on one side and the component that uses it on the other. Put them all in a hat, pull them out one-by-one and read the side that comes out first and remember what is written on the other. Sometimes I have to match the IRQ to the component, sometimes vice-versa.

    OK.Maybe I can help a little with trying to remember IRQ's..

    Remember this...4 3 4 3 7 5

    COM 1 - IRQ 4
    COM 2 - IRQ 3
    COM 3 - IRQ 4
    COM 4 - IRQ 3
    LPT 1 - IRQ 7
    LPT2 - IRQ 5

    4 3 4 3 7 5

    The remaining IRQ's will fall into place around the,try it my friend.

    For addresses remember this 3 2 3 2 3 2 FF EE

    COM 1 - 3FH8
    COM 2 - 2FH8
    COM 3 - 3EH8
    COM 4 - 2EH8
    LPT 1 - 378
    LPT 2 - 278

    3 2 3 2 3 2 FF EE

    Hope this makes sense .. :biggrin

    What a great title, that's exactly how my mind works - or doesn't. I learn something from A+ and then forget a previous chapter. aaaaaaaahhhhhhhhhh

    Mnemonics work for me, (that and spell checker). :D

    Malnomates - well put !! That's how I remembered it for A+ (back in the day). I can still recall yet, proving the point that a well-devised method always sticks (as long as it suits you in the first place).
