You know... the OSI model is pretty complicated. Here is the wiki on the Data Link Layer. It's pretty spot on:
http://en.wikipedia.org/wiki/Data_Link_Layer
"Data Link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium."
This is mostly association of the destinations of packets for each MAC. Like... each port on a switch has a MAC, and each computer's WAN connection has a MAC, and wireless cards and the like. It's meant to keep many many objects in the world and on the same network pretty much unique. There is such a thing as a MaC spoof, but that is a different topic.
Really, take the time to read all the OSI model stuff on wiki, and you'll do yourself a world of good, especially if you're trying to break into the industry. It's like knowing the alphabet. It really helps to know the OSI model for troubleshooting connections (and general problems) at different levels. Hell... even PC problems.
