The second part of the story. Keith Barker walks you through each of the layers of the OSI model by function:

Layer 3 = Router
Layer 2 = Switch
Layer 1 = Cables, Hubs, Repeaters

Also the terms for the data at each level are discussed:

Layer 4 = Segments of data
Layer 3 = Packets of data
Layer 2 = Frames of data
