Any two from:

serial – one bit sent at a time // bits sent sequentially – over a single wire – synchronous or asynchronous [2]

Any two from:

parallel – several bits / a byte sent at a time – using many / multiple wires – synchronous [2]

– serial Any two from:

– serial data transmission more reliable over long distances – less likely for the data to be skewed/out of synchronisation – less interference as only a single wire – it is a cheaper connection as only single wire needed // cheaper to set up – a fast connection is not required as a printer is limited by its printing speed [3]
