Annotate the “OSI Model Diagram,” according to the following instructions:

1. In the center of the diagram, beneath each label place a one- or two-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.

GCU style is not required, but solid academic writing is expected.

Refer to “ITT-116 OSI Annotation Scoring Guide,” prior to beginning the assignment to become familiar with the expectations for successful completion.

You are not required to submit this assignment to LopesWrite.
