i got these two things with my motherboard that i won on ebay:

problem is i have no idea what they are or even if they fit in the mb (cant find a slot for them)
i had asked my ICT teacher he said the one looks like the internal speaker, or they could both be blankers (whatever they are)....
all i can tell is that one has a speaker looking box on it and the other has a internet wire socket on it, and says something about networking on the metal peice?

here is the motherboard i orderd, any help on what it is and if it fits in my mb will be greatly appreciated.
