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