Demultiplexing serial transmission Example of connectionless multiplexing and demultiplexing Data transmission parallel transmission Long range transfers, almsot all external components connected to another device, connecting a phone/keyboard/printer to a laptop. Multiplexing Uses light signals transmitted through fiber optic channels whereby very narrow bands of light are combined from several sources to make a wider band of light. Takes data stream from one high-speed line and breaks into portions and sends over several lower-speed lines simultaneously. Frequency Division Multiplexing (FDM) Transport Layer
