Assignment

A. Read through the Case Project 2-3 located on page 74 of the text. Answer the following questions in a 500-1000 word paper.

1. Describe how OSI model layers can affect a network's design and networking in general.

2. There are two different types of switching technologies available in today's market. One lives on one layer while the other resides in a different layer of the OSI model. Locate these switching technologies, describe the differences in functionality, and relate those differences to the functions inherent within the OSI model. Your OSI model annotation document from week 1 will be valuable.

3. How can the OSI model be useful during troubleshooting processes?

B.

1. In the center of the diagram, beneath each label place a 1 or 2-word descriptor for that layer.

2. Create a list of at least 10 networking devices. Add those devices to their proper layer on the left side of the diagram.

3. Create a list of at least 40 protocols. For each protocol, determine its port number. Add each protocol to the appropriate layer on the right side of the diagram.

Note: Some protocols span multiple layers. Indicate these protocols by adding +/- to the annotation.
