[Solved] Which of the following is a correct statement about layered network models? — Ans: Layers communicate only with the layer directly above or below | Computer Networks

Computer Networks - OSI and TCP/IP Models

Which of the following is a correct statement about layered network models?

ALayers communicate only with the layer directly above or below

BAll layers share the same protocols

CLayers skip communication to speed up processing

DEach layer performs multiple unrelated tasks

Step-by-Step Solution

Solution:

Step 1: Recall how layers interact in a network model
Each layer communicates only with the layer directly above or below it to keep tasks organized.
Step 2: Identify the correct communication rule
This strict communication path helps maintain clear boundaries and simplifies troubleshooting.
Final Answer:
Layers communicate only with the layer directly above or below -> Option A
Quick Check:
Layer communication is only with adjacent layers [OK]

Quick Trick: Remember: layers talk only to neighbors [OK]
