Computer Networks - OSI and TCP/IP Models
How does the OSI model's Data Link layer compare to the TCP/IP model's layers in terms of functionality?
AData Link corresponds to Internet layer handling routing
BData Link corresponds to Network Interface layer handling physical addressing
CData Link corresponds to Transport layer handling error recovery
DData Link corresponds to Application layer handling user data
Step-by-Step Solution
Solution:
  1. Step 1: Understand OSI Data Link layer role

    The Data Link layer manages physical addressing and local network communication.
  2. Step 2: Match with TCP/IP layer

    The TCP/IP Network Interface layer performs similar functions including physical addressing.
  3. Final Answer:

    Data Link corresponds to Network Interface layer handling physical addressing -> Option B
  4. Quick Check:

    Data Link = Network Interface [OK]
Quick Trick: Data Link = Network Interface layer functions [OK]
Common Mistakes:
MISTAKES
  • Confusing Data Link with Internet layer
  • Mixing Transport with Data Link
  • Assigning Application layer functions incorrectly
