MULTIPLEXING Every computer has a port to connect a colloquy line or cable from a off-base device. Computers have limited number of ports, so multiplexers are used. They chord signals from multiple terminals and put them all on a grinder parleys line. This increases the efficiency of communication and is cost-effective. The communication line is go against up into different sections and the data from each terminal is coded and move and because received, decoded and directed to the correct section from where it came from. There are four-spot commonly used types of multiplexing, the first is (FDM) frequency division multiplexing.
FDM divides the bandwidth of the communicatio n line so that each terminal can alternate data. The individual terminals are separated from guardbands to ensure the signals do non interfere with each other. Multiplexers often have external modems or internal modems built in to convert the data to additive before transmission takes place. The local cable televisi...If you want to sustain a full essay, order it on our website:
