So, I've decided I wanna take the A+ exam. I've been going over some learning material and have started to come up with some unanswered questions. With no one to turn to I thought this would be the perfect place to ask! If any one else has questions of the inner workings of the computer please feel free to ask away! ;) Ok here goes:

1. I've gotten into the bus structure and I'm wondering: What's the difference between LPT, I/O port, and IRQ? (e.g. LPT1 I/O port 378 IRQ 7) I understand thats all the same line, Printer Port 1 but what do they all mean!?!?

Thanks
Hoobie :)
 
2. Where can I go on my computer to see the assigned IRQ channels so I can get a better idea? I'm running XP.

2. Control Panel>Sytem Properties>Device Manager>View>Resources by connection.
