USB : Overview    USB Is Like A Railroad  

All of the Divisions (Interfaces) are physically located in Hidville (our USB peripheral device).

In PC City(the PC), our company has a warehouse close to the train station, where our freight (our data) is placed when it is taken off the IN-bound train, or where it is placed by us before it gets loaded onto an OUT-bound train.

The directions IN and OUT are always relative to PC City (the PC).
