[Solved] Which of the following is the correct order of layers in the OSI model from top to bottom? — Ans: Application, Presentation, Session, Transport, Network, Data Link, Physical | Computer Networks

Computer Networks - OSI and TCP/IP Models

Which of the following is the correct order of layers in the OSI model from top to bottom?

AApplication, Presentation, Session, Transport, Network, Data Link, Physical

BPhysical, Data Link, Network, Transport, Session, Presentation, Application

CApplication, Session, Presentation, Transport, Network, Data Link, Physical

DPhysical, Network, Data Link, Transport, Session, Presentation, Application

Step-by-Step Solution

Solution:

Step 1: Recall OSI layer order
The OSI model layers from top to bottom are Application, Presentation, Session, Transport, Network, Data Link, Physical.
Step 2: Match options with correct order
Application, Presentation, Session, Transport, Network, Data Link, Physical matches the correct top-to-bottom order exactly.
Final Answer:
Application, Presentation, Session, Transport, Network, Data Link, Physical -> Option A
Quick Check:
OSI top-to-bottom = B [OK]

Quick Trick: Remember OSI top layer is Application, bottom is Physical [OK]
