Lab Duration

It will take approximately 1 hour to complete this lab.

Exercise 1 - Understand the OSI model

In order to more fully understand the layered model and to be able to apply this to the lab activities that will take place in subsequent exercises, this exercise will give you a brief overview of layered networking models. In this exercise, you will review the structure and function of the OSI model, and you will compare it to another layered model, the TCP/IP model. You will also see how the OSI model structure can be used to aid in troubleshooting.

Learning Outcomes

After completing this exercise, you will be able to:

  • Explain the structure of the OSI model

Exercise 2 - Layers 1 to 3 of the OSI model

In this exercise, you will examine various portions of the network, and you will identify them as part of specific layers within the OSI model. This exercise deals with the first three layers of the OSI model, namely the Physical, the Data Link, and the Network layers.

Learning Outcomes

After completing this exercise, you will be able to:

  • Demonstrate how the OSI model compares with the TCP/IP model

Exercise 3 - Layers 4 to 7 of the OSI model

In this exercise, you will examine various portions of the network, and you will identify them as part of specific layers within the OSI model. This exercise deals with layers 4 to 7 of the OSI model, namely the Transport, Session, Presentation, and Application layers.

Learning Outcomes

After completing this exercise, you will be able to:

  • Review some of the components that make up the OSI model
