The diagram inside the back cover of this book provides an illustration of the new network model for Terra Flora. All primary services and computers systems for Terra Flora are shown. For brevity, only a representative sample of worldwide retail operations is shown.
Each computer is labeled with a name that includes the following information.
The first line below each computer icon lists the computer name, which has 12 characters. These follow specific naming conventions, with each character representing additional information about the computer.
The first two characters indicate the domain of which the computer is a part. Terra Flora uses the following domain symbols.
The five characters following the domain symbol represent the operating system that the computer is running. Table 4.3 lists the five-character codes and the systems they represent.
