Computer Networks - OSI and TCP/IP Models

Which advantage does a layered network model provide when designing complex communication systems?

AIt allows independent development and testing of each layer

BIt requires all layers to be updated simultaneously

CIt eliminates the need for protocols between layers

DIt merges all network functions into a single layer

Step-by-Step Solution

Solution:

Step 1: Understand layered model purpose
Layered models divide network functions into separate layers.
Step 2: Identify benefits
This separation allows each layer to be developed and tested independently without affecting others.
Final Answer:
It allows independent development and testing of each layer -> Option A
Quick Check:
Independent layer development simplifies design [OK]

Quick Trick: Layers isolate functions for easier design and testing [OK]
