Quizplus · Accepted Answer

PDU stands for Protocol Data Unit, which is the unit of information used by each layer in the OSI model to communicate with the layer above or below it. Each layer adds its own header to the PDU received from the layer above it, forming a new PDU that gets passed down to the next layer. Therefore, the term PDU is not specific to any particular layer but rather a general term that refers to the unit of information used by each layer.
