Building a Centralized Warehouse: File Transfer

Building a Centralized Warehouse: File Transfer

As you saw in the previous section, e-mail has some obvious comparison points with snail mail. The next application, file transfer, does not compare directly with a noncomputing example, but it does work a little like a warehouse that a company might use to store goods. Imagine that a company has a bunch of stuff, and many people inside the company might need some of the stuff from time to time. Some of the stuff is big, and some of the stuff is small. So, the company leases warehouse space and puts its stuff in the warehouse. Then the company gives everyone a key, and anyone who needs some stuff can go get it when needed. Figure 8-9 shows the general concept.
