PDU, or Protocol Data Unit, refers to a unit of data specified in a protocol of a given layer in the OSI model. It encompasses the headers and payload relevant to a specific layer, facilitating communication across network systems. For example, in the transport layer, a PDU is called a segment, while in the network layer, it is referred to as a packet. Each layer's PDU serves its distinct purpose and adheres to the rules of the corresponding protocol.

Identify PDU in each layer of OSI?
In the OSI model, the Protocol Data Unit (PDU) varies by layer. At the Application layer (Layer 7), the PDU is called a message. In the Transport layer (Layer 4), it is referred to as a segment (or datagram in connectionless protocols). The Network layer (Layer 3) uses packets, while the Data Link layer (Layer 2) uses frames. Finally, at the Physical layer (Layer 1), the PDU is a bit.
Explain the difference between a PDU and a datagram?
A PDU (Protocol Data Unit) is defined by which layer it is in. In the physical layer and network layer, it is synonymous with the packet, in the data link layer, it is the frame. In the transport layer, it is a datagram for UDP. A datagram holds one or more PDU's, as it is the basic unit of transferring information via packet switching.
