Computer Networking What is the main reason the OSI model was created? So different networks could communicate. To create a layered model larger than the DoD model. So Cisco could use the model. So application developers can change only one layer's protocols at a time. So different networks could communicate. To create a layered model larger than the DoD model. So Cisco could use the model.

Computer Networking The difference between a multiplexer and a statistical multiplexer is Multiplexers use Time Division Multiplexing (TDM) while statistical multiplexers use Frequency Division Multiplexing (FDM) None of these Multiplexers often waste the output link capacity while statistical multiplexers optimize its use Statistical multiplexers need buffers while multiplexers do not need buffers Multiplexer use X.25 protocol, while statistical multiplexers use the Aloha protocol Multiplexers use Time Division Multiplexing (TDM) while statistical multiplexers use Frequency Division Multiplexing (FDM) None of these Multiplexers often waste the output link capacity while statistical multiplexers optimize its use Statistical multiplexers need buffers while multiplexers do not need buffers Multiplexer use X.25 protocol, while statistical multiplexers use the Aloha protocol ANSWER DOWNLOAD EXAMIANS APP
