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