Your instructor might want you to organize in groups for this project. This chapter included a few real-world examples that use a layered approach to describing a process. See whether you can come up with another process that can be described in layers. You should give a presentation to the class with a detailed description of the layered process you decide on.

Case Project 7-3

You want to transfer a document from one computer to another, and you want the document to be encrypted. The destination computer is on another network, so you know data has to travel through one or more routers. The network technology on your network is Ethernet, but the technology on the destination network is Wi-Fi. From what you have learned about networking, should this document transfer work? Why or why not? Which layers of the OSI model are involved in the italicized parts of this description?
