The International Organization for Standardization (ISO) developed a model to help standardize and understand computer networks. Before this model was introduced, networks for the most part could not communicate with one another easily and became islands within organizations. The OSI model is widely used in industry as a way to ensure compatibility with other vendors' network equipment and in the education setting to teach the complex nature of computer networking in a layered approach.

1. Using the Internet, find an instance where the OSI model has been used to ensure the compatibility of network architecture.

2. Write a report based on your findings.

3. In your report, describe how the OSI model helped two separate vendors design equipment that would communicate well.
