	A '''bridge''' is a type of [[packet switch]] which is fundamentally different from a [[router]]. It effectively unifies two otherwise separate [[physical network]]s; a [[host]] sending a [[packet]] cannot tell whether the destination [[network interface]] is on the same physical network as it is, or on another one, which is connected to its physical network through a bridge. The two physical networks must thus share a unified [[address space]].		A '''bridge''' is a type of [[packet switch]] which is fundamentally different from a [[router]].
