Explanation

In layered architecture, each layer communicates with its peer layer on another device. The data unit exchanged between peer layers is called a Protocol Data Unit (PDU). Different layers have different PDU names - segments at transport layer, packets at network layer, frames at data link layer - but collectively they're all PDUs.
