What is the correct sequence of PDUs at each layer?

medium📝 Analysis Q13 of 15
Computer Networks - OSI and TCP/IP Models
Consider this simplified data flow: Application data is passed down to the Transport layer, then to the Network layer, and finally to the Data Link layer. What is the correct sequence of PDUs at each layer?
APacket -> Segment -> Frame
BSegment -> Packet -> Frame
CFrame -> Packet -> Segment
DBit -> Segment -> Packet
Step-by-Step Solution
Solution:

  1. Step 1: Identify PDUs for each layer in order

    Transport layer uses Segment, Network layer uses Packet, Data Link layer uses Frame.

  2. Step 2: Arrange PDUs in the order data passes down

    Data flows from Transport (Segment) -> Network (Packet) -> Data Link (Frame).

  3. Final Answer:

    Segment -> Packet -> Frame -> Option B

  4. Quick Check:

    Transport=Segment, Network=Packet, Data Link=Frame [OK]
Quick Trick: Remember data flows: Segment, Packet, then Frame [OK]
Common Mistakes:
MISTAKES
  • Mixing order of PDUs
  • Confusing Packet and Segment
  • Including Bit as a PDU in this sequence
