What is the PDU of the Presentation Layer?

Explanation:
In the Presentation layer the information handed down from the upper layers is treated as a payload rather than wrapped with a new header. This layer focuses on how data is represented—encoding, compression, and encryption—so it changes the format of the data but does not add its own protocol-specific header. Because of that, the PDU at this level is simply the data from the layer above. Lower layers add their own PDUs—segments at the Transport layer, packets at the Network layer, frames at the Data Link layer, and bits at the Physical layer—while the Presentation layer passes along and transforms the payload.
