A switch is designed with chips which are solely used for fast switching capablility,the bridge uses software which runs on top of hardware which hence takes longer to perform the switching function.
A Switch generally has more ports then a bridge and also have more configuration possibities, a switch is generally considered as an inteligent bridge.

Ed summed it up pretty well.

A switch can also be referred to as a multiport bridge.

Yeah and an apple can also be called a green orange.

A switch is referred to as a multiport bridge. A ways back, a bridge had one input and one output. As the technolgy advanced and needs became greater the multiport bridge or switch was developed. A switch is nothing but a more advanced multiport bridge.
