An energy company with headquarters in Dallas, Texas, is thinking about developing a system to track the efficiency of its oil refineries in North America. Each week, the ten refineries$$as far as Valdez, Alaska, and as close as San Antonio, Texas$$will upload performance data via satellite to the corporate mainframe in Dallas. Production managers at each site will use a personal computer to connect to an Internet service provider and access reports via the Web. Create a high$-$level network model that depicts the locations that have components supporting this system.
