Introduction of Multiplexing. Whenever the transmission capacity of the medium linking two device is greater than the transmission needs of the device, the link can be shared..

Allows the user to move freely around the office or campus and still remain connected to the network. Introduction. One of the major functions of physical layer is to move data in the form of electromagnetic signals across a transmission medium.. Thus, the data must be transformed to electromagnetic signals to be transmitted.. Computer Networks Physical Layer Based on slides from Zoltán Ács ELTE and D.
