Hello Larry

The hub is to connect your work stations to a Local Areea Network (LAN), in a same building.  The switch is when your LAN is too big, yo segment it in smaller sections to get a better speed.  The router is to inter connect two LANs that are separated by distance.  The router in a sense has a similar effect like a switch, but if you are in the same building is anti-economic to segment your LAN with routers.

I hope I have been helpfull with this short explanation
