a. Suppose you own a widespread chain of turkey tartare and sushi fast-food joints. Your tores are scattered all over the mainland United States and Canada. There are also a few stores in Western Europe. The computers in each store must communicate with the central operation in Texas on a regular basis, but not with each other. Design a network that would meet the requirements of your company.

b. For each of the links in this network, describe a technology (medium and signaling method) that would be suited to this application.
