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 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.
Significance of the right PDU and its certification?
The effect of rapid digitalization across all industries has forced companies to act quickly and install next-generation IT infrastructure at their desired locations. This applies to core IT firms, and data centres as well. Availability and security are the key criteria for any firm to continue normal operations, as operations are greatly affected without a well-functioning IT system. A reliable power supply is a crucial element of any firm largely dependent on IT. And that is where PDU or Power Distribution Units play a major role, as they are considered the heart of rack solutions. Selecting the right rack PDU for the application can be difficult especially without any information on the equipment that will go into the rack. Industries cannot afford to use low-quality PDUs as they greatly affect the critical equipment going into the rack. Here are some important factors to consider when selecting a PDU for your racks… Power rating and safety The first thing to determine when selecting a PDU is the power consumption of the equipment that goes inside the rack. This helps in determining the capacity of the PDU. Best practices in the industry involve bifurcating the circuit into 16A each with proper circuit breakers. These circuit breakers have to be designed in such a way that the issue of accidental tripping is completely eliminated. Certifications It is highly important that the PDU adheres to all basic certifications for safety measures, like UL, RoHS, CB, CE, and LVD. Certified PDUs are recognized to be the best-in-class for quality as they comply with all the international standards. They are manufactured in accordance with the safety guidelines followed globally, with reliable circuit design for better functioning. Moreover, certified PDUs, like ones from Netrack India, greatly reduce the risk of downtime and increase dependability. Variants of the PDU Since the PDUs are available in multiple socket configurations like the Indian round pin, multipin, IEC, UK flat pin, the user has to choose the PDU’s sockets based on the pin configuration at equipment level. That apart, one can also choose from PDUs available in metered or managed configuration. One of the major advantages of such managed or metered configuration is that they provide information on the power consumption and energy management. These factors play an important role in the planning of power capacity. Selecting the right PDU requires a good analysis of its quality or certifications, as these PDUs will be powering your mission critical equipment.

Explain about protocol data unitidentify PDU in each layer of OSI?
A Protocol Data Unit (PDU) is a unit of data specified in a protocol of a given layer of the OSI model. Each layer has its own PDU: at the Application layer, it's called a message; at the Transport layer, it's a segment (or datagram in UDP); at the Network layer, it's a packet; at the Data Link layer, it's a frame; and at the Physical layer, it's a bit or symbol. These PDUs help in managing and encapsulating data as it traverses through the layers of the OSI model.
Difference between UDP and PDU?
PDU Information that is delivered as a unit among peer entities of a network and that may contain control information, address information, or data. UPD The User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite, the set of network protocols used for the Internet. With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths
What is the PDU at each layer?
Application layer: Data Presentation layer: Data Session layer: Data Transport layer: Segment (TCP) or Datagram (UDP) Network layer: Packet Data Link layer: Frame Physical layer: Bit
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.

The PDU at the Transport layer is called?

What is the difference between PDUs and contact hours and which you need to become PMP certified?
They refer to the same thing. PDU and Contact hours both refer to the training/education you need to undergo in order to be eligible to take the PMP Exam or to continue holding on to your PMP Credential
