The Broadcast Domain is equal to or greater than the Collision Domain.

All ports on a hub are in the same collision domain (and therefore, also the same broadcast domain).

All ports on a switch are in the same broadcast domain, but separate collision domains.

Hubs connect disparate broadcast domains together.

Does anyone actually manufacture hubs any longer? The concept of collision domains comes from early Ethernet days when many devices shared a common media, coax cable. Also, routers connect different broadcast domains. –  dbasnett Jul 15 '10 at 11:59
