you will examine the role of the OSI model in network design.The OSI model is not a network architecture, and it does not constitute network specifications. The OSI model serves as a guideline for network design and helps in representing how a network functions.Continuing with the course project you started in Week 1, on the basis of your research and reading in this week, complete the following tasks:Map the layers of the OSI model to the actual processes required for your scenario as identified in W1 Project. Use the OSI model as your network design reference.Based on the updates to your network design, update the vendor and costs table that you created in W1 Project.Finally, add a network process diagram to your proposal.Note: You may want to try a different drawing tool for that purpose.
