In networking, PDU means "protocol data unit", and it is the generic name of the "packets" of data used at different levels of the network. Using the numbering of the OSI layers:
At layer 2, the PDUs are called "frame". Example: An Ethernet frame, a frame-relay frame.
At layer 3, the PDUs are called "packets". Example: An IP packet.
At layer 4, the PDUs are called "segments". Example: A TCP segment, a UDP segment.

The PDU at the Network layer is called?
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.
What are the parts of a pdu that are always present in any pdu?
The Header and the payload The Header and the payload
What is the layer 4 UDP PDU called?
Datagrams TCP/IP layer 4 PDU's are called segments...
The PDU at the Transport layer is called?
The PDU (protocol data unit) @ transport layer (e.g. TCP or UDP) is called as 'segment' .

What is the PDU of the network layer?
What is a PDU? corruption of a frame during transmission data reassembled at the destination retransmitted packets due to lost communication a layer specific encapsulation
Can you plug a ups into a pdu?
yes but not the other way around
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.
What does a PDU do in networking?
(1) Short for Protocol Data Unit. The term used to describe data as it moves from one layer of the OSI model to another. In this reference, PDU is often used synonymously with packet.(2) Short for Power Distribution Unit. An electrical device used to control the distribution of power to individual loads. The PDU may be a stand-alone controlled device or it may be integrated directly into the UPS (uninterruptiblepower supply).Took it from a good search, sources have been added after searching PDU.
