Question

Starting with the layer that is closest to the user what is the correct order of layers of the OSI model?

a. Physical, Data Link, Network, Transport, Session, Presentation, Application
b. Presentation, Data Link, Network, Transport, Session, Physical, Application
c. Application, Presentation, Session, Transport, Network, Data Link, Physical
d. Application, Physical, Session, Transport, Network, Data Link, Presentation

Answer 1

The correct order of layers in the OSI model, starting with the layer closest to the user, is Application, Presentation, Session, Transport, Network, Data Link, Physical.

Step-by-step explanation:

The correct order of layers of the OSI model, starting with the layer closest to the user, is: Application, Presentation, Session, Transport, Network, Data Link, Physical (option c).

The OSI model is a conceptual framework that standardizes the functions of a communication system into seven layers. Each layer performs specific tasks and communicates with the adjacent layers through well-defined interfaces.

For example, the Application layer (Layer 7) is responsible for providing network services to user applications. The Physical layer (Layer 1) deals with the physical transmission of data, such as electrical or light signals.
