Transport Layer serial transmission Long range transfers, almsot all external components connected to another device, connecting a phone/keyboard/printer to a laptop. Takes data stream from one high-speed line and breaks into portions and sends over several lower-speed lines simultaneously. Application layer Frequency Division Multiplexing (FDM) source IP address source port number destination IP address destination port number Demultiplexing Integrated circuits, busses, connecting internal hard disk to a CPU.
