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!

Can't really ad any more- just keep reading and looking at flash cards

 

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!

Lord Deckard.

 

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 ..

 

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).

Mother very thoughtfully made a jelly sandwich under no protest. (mercury, venus, terra, mars, asteroids, jupiter, saturn, uranus, neptune, pluto) - Good in astronomy classes.

 

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).

 

Thanks for the tips,I'll try some of them out to see which ones work the best for me.The coures i'm doing is with computeach and at the end I'm supposed to be a senior networking proffessional.

 

LOL! i can guarantee you it wont make you a "senoir" NP. or have you that much experience under your belt?
