Im studying for the A+, and these seem like basic questions. If the A+ is where you are getting the questions from, Im taught when a question seems too basic, it could be a trick question, lol.

Im not done studying so I could be wrong, but here are my answers:

Question 1:

DOS (Disk Operating System) <- I would go with this one

it could be CP/M (Control Program for Microcomputers) but I highly doubt it.


Question 2:

The question seems to have a rather wide scope. I would go with:
System Bus , but, this answer also has a really wide-scope and "System bus" could actually mean many things.
If you have to be more specific:
Super I/O Chip

Question 3:

Interrupt Controller

Hope that helps, let me know if that is what you needed or helps, Josh.

PS: Are the questions from an exam or...what?
