easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify Physical layer function
The Physical layer transmits raw data as electrical or optical signals.Step 2: Determine PDU name
At this layer, the PDU is called a 'Bit' because data is sent bit by bit.Final Answer:
Bit -> Option CQuick Check:
Physical layer PDU = Bit [OK]
Quick Trick: Physical layer sends data as bits [OK]
Common Mistakes:
MISTAKES- Choosing Frame or Packet instead of Bit
- Confusing with higher layer PDUs
