During data transmission, which PDU is created by the Data Link layer before sending data to the Physical layer?
APacket
BFrame
CSegment
DBit
Step-by-Step Solution
Solution:

  1. Step 1: Identify Data Link layer output

    The Data Link layer packages data into Frames.

  2. Step 2: Confirm PDU sent to Physical layer

    Frames are then converted into Bits by the Physical layer.

  3. Final Answer:

    Frame -> Option B

  4. Quick Check:

    Data Link layer PDU = Frame [OK]
Quick Trick: Data Link layer creates Frames before Physical layer [OK]
Common Mistakes:
MISTAKES
  • Choosing Packet or Segment instead of Frame
  • Confusing Physical layer PDU
