Hi, you should have a good understanding of the OSI model when you discuss encapsulation. The top 3 layers pass their data down to the transport layer, the transport layer encapsulate the data into a "segment". The segment is passed down to the network layer, the network layer add the IP and routing and then creates a "packet" the packet is passed down to the datalink layers which adds layer 2 addressing and protocols and creat a "frame". the frame is passed down to the physical layer which places the information from the frame onto the wire in "bits".
