Layer 2 is divided into the LLC and MAC sublayers.
In computer networking there is a seven layer OSI model and the LLC or logical link control layer is a data communication protocol layer which is the upper sublayer of the second OSI layer known as the data link layer. The main characteristic of the LLC sublayer is that it provides multiplexing mechanisms that allow for a number of different network protocols like IPX, AppleTalk and IP to work over the same network as well as allow them to exist together within a multipoint network.
Data link layer
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
i believe (not quite sure) that it is at the application layer (layer 1)

OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
