Routers .vs. Switches
Don't try telling a manager about the layer model - it confuses them and wastes your time. What you should do is compare it to a model which they might understand, i.e. road traffic. A switch is traffic lights, which lets people in the correct lane go into the corresponding street. A router is a policeman, who does the above, but also notices that the car three back is the Queen's Roller and treats her with priority. He lets her drive on the footpath and run over pensioners, which is why routers are more expensive and hubs are like driving in Italy.
