Repeaters and Hubs are Physical Layer Devices. Repeaters amplify analog
signals to reduce attenuation. Hubs provide multiple connection points for
a single network segment. Hubs are sometimes called multi-port repeaters.
Switches and Bridges are Layer 2 devices. They look at the Layer 2 address
(MAC address), and make decisions about the destination of a packet based on
the information contained therein.
