Routers operate at the network layer. The term router implies that this entity
not only moves information from one network to another, but it can also make
decisions about what route the information should take.
Hubs operate at the physical layer. There are two kinds of Hubs, Pasive Hub and Active Hub. A pasive Hub is a resistive divisor.
An active Hub repeats and regenerate the signal in a LAN (i.e. Token Ring, ARCNET or Ethernet ) Hubs are usually hardware devices, while routers can be implemented in either hardware and software.
