Computer Networks - Physical and Data Link Layer

Consider this simplified Ethernet frame structure:
Destination MAC | Source MAC | Type | Payload | CRC
Which part is responsible for detecting errors in the frame?

AType

BPayload

CCRC

DSource MAC

Step-by-Step Solution

Solution:

Step 1: Understand frame fields
The CRC (Cyclic Redundancy Check) field is used to detect errors in the frame data.
Step 2: Differentiate other fields
Type indicates the protocol, Payload carries data, and Source MAC is the sender's address, none detect errors.
Final Answer:
CRC -> Option C
Quick Check:
Error detection = CRC [OK]

Quick Trick: CRC checks for errors in Ethernet frames [OK]

Common Mistakes:

MISTAKES

Confusing Type field with error detection
Assuming Payload includes error checking
Mixing Source MAC with error detection
