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.

Which option shows the correct order of PDU de-encapsulation when a device receives messages from a network?
Frame, packet, segment, and lastly data shows the correct order of PDU de-encapsulation when a device receives messages from a network.
What is a PDU?
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
Which PDU format is used when bits are received from the network medium by the NIC of a host?
frame
A device used as a power source?
A generator.
What is it called when only one PDU can cross a wire in each direction at any given time?
LLC in LAN Technologies (4) LLC protocol - HDLC protocol Type 3 of operation - each transmitted PDU is acknowledged: - a new unnumbered PDU is defined: Acknowledge Connectionless (AC) PDU - user data are sent in AC command PDUs an must be ack using an AC response PDU. - to guard against the lost PDUs, a 1-bit sequence number is used: the sender alternates 0 and 1… - only one PDU in each direction may be outstanding at any time
What is the layer 4 UDP PDU called?
Datagrams TCP/IP layer 4 PDU's are called segments...
What device is used to create electrical power?
Usually a generator.
What is the difference between a PDU and a datagram?
This is a more generic term that is often used in describing protocols that function at higher levels of the OSI model, ususally the network layer and up. Datagram is a less specific term than PDU.Datagrams contain logical addressing information, such as an IP address, logical connection identifiers, such as port numbers, and data that came from a computer application. The UDP protocol does not guarantee delivery of the datagrams.A PDU is a Power Distribution Unit.I have added a link to a PDU from Intro Delta to show you what one is.
