ONE:Now that you have read the chapter about the OSI model, how would you change it? Are there inefficiencies or redundancies in the model?

TWO:Learning Objectives

In this lab, you’ll examine the layers of the OSI seven-layer model and the TCP/IP model. When you’ve completed this lab you will be able to

● Explain why layered models are used to describe data communication.

● Identify each of the seven layers of the OSI model. 

Lab Materials and Setup

The materials you need for this lab are

● The Mike Meyers’ CompTIA Network+ Guide to Managing and Troubleshooting Networks textbook

● Pencil and paper

Instructions

Work through the following tasks to investigate the details of network data delivery using the OSI seven-layer model. 

Task 1: Answer the following questions.

1. How does the concept of layers describe flow of information or communications?

2. How are layers used to describe data communications? 

3. What is a mnemonic used for remembering the OSI model? 

4. What is the OSI model and what are its benefits?

5. What are some advantages of the OSI model? 

6. What is a PDU?

7. Explain data encapsulation.
