The difference between a multiplexer and a statistical multiplexer is

Multiplexer use X.25 protocol, while statistical multiplexers use the Aloha protocol

Statistical multiplexers need buffers while multiplexers do not need buffers

Multiplexers often waste the output link capacity while statistical multiplexers optimize its use

None of these

Multiplexers use Time Division Multiplexing (TDM) while statistical multiplexers use Frequency Division Multiplexing (FDM)

What is the main reason the OSI model was created?

To create a layered model larger than the DoD model.

So different networks could communicate.

So application developers can change only one layer's protocols at a time.

So Cisco could use the model.
