Matching Pairs Digital Data Communication Online version Techniques and Multiplexing by Aidora Abdullah 1 Bits are sent consecutively over a single wire. 2 Uses of parallel transmission 3 The layer in the OSI reference model which is the junction for multiplexing and demultiplexing. 4 Multiplexing technique to transmit analog signals. 5 6 7 Example of half-duplex transmission 8 Disadvantages of parallel transmission 9 Bits are sent simultaneously over a number of lateral wires. 10 11 Example of simplex transmission 12 The 4-tuple to identify a TCP socket in connection-oriented multiplexing and demultiplexing 13 Demultiplexing delivers received segments at the receiver side to this layer in the OSI reference model. 14 Wavelength division multiplexing (WDM) 15 Sending data from one particular device to another, and measured in bits. 16 Example of duplex transmission 17 The form that data travels in digital devices. 18 Uses of serial transmission 19 Time Division Multiplexing 20 Frequency Division Multiplexing (FDM) Multiplexing Data transmission source IP address source port number destination IP address destination port number Example of connectionless multiplexing and demultiplexing Application layer Demultiplexing 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. 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. Integrated circuits, busses, connecting internal hard disk to a CPU. serial transmission parallel transmission Transport Layer Data can be lost, receiving device has to reorder data, crosstalk.
