Serial Connection
- it transmit one bit at a time
- less crosstalk issue because there are fewer lane in proximity
- don't have timeskew which means they can reassemble the bits by the time it arrived to the destination
- good to support fast transmission because the information will not mix up and easily reassemble at the endpoint
Parallel Connection
- it transmit several bit at a time
- having crosstalk issue because there are more than one lane and there will chance of the lane being interrupted with one another.
- having timeskew issues since in parallel connection, all the bits will not arrive at the same time so, they must wait for all the bits to arrive and then they are able to reassemble it
- difficult to support fast transmission because it will cause longer time to reassemble the data
