Q. Explain Full Duplex data transmission?
- Have two separate Communication channels as well as use each one for simplex Data traffic (in different directions).
- If this is through we have two separate physical circuits each with a "forward" channel (for data) and a "reverse" channel (for acknowledgements).
- In both cases the bandwidth of the reverse channel is approximately entirely wasted and in effect the user is paying for two circuits but using only the capacity of one.
- A better idea is to utilize the same circuit for data in both directions and in this model the data frames from A to B are intermixed with the Acknowledgement frames from A to B.
- By gazing at the kind field in the header of an incoming frame the receiver can tell whether the frame is data or acknowledgement.
