Have you looked here:

http://en.wikipedia.org/wiki/Trap_(computing)
http://en.wikipedia.org/wiki/Interrupt

And according to wiki
exception: An action that is not part of ordinary operations or standards

Was that a homework by the way?

No ....It is not home work. As said in my intro email...I am learning operating system concepts and learning linux. I am a DSP engineer... I did spent my time in coding C and assembly and now I am learning towards embedded side.

I am going through embedded sw primer text and got diverted and searching net for thorough understanding and got more confused with these terms. I though I would better ask in LQ. Thats it. Thanks btw
