Encoding methods and Modulation schemes 25.P.1 Computers use digital signalling‚ digitals signals are represented by the base 2 numbering system “Binary”. Binary bits are shown as 1 or 0‚ where 1 means ON and 0 means OFF. In a network where digital devices exist‚ digital signalling will be used. Dependant upon the encoding method used‚ a high voltage on a communications medium can represent a logical 1 and a low voltage of can represent a logical 0. Different methods of encoding exist these

between source and destination are traversed. 12.7 Advantages: (1) An adaptive routing strategy can improve performance‚ as seen by the network user. (2) An adaptive routing strategy can aid in congestion control. Because an adaptive routing strategy tends to balance loads‚ it can delay the onset of severe congestion. Disadvantages: (1) The routing decision is more complex; therefore‚ the processing burden on network nodes increases. (2) In most cases‚ adaptive strategies depend on status information
