Difference between Switch and Hub.

Could someone explain to me the difference between a switch and a hub.
Is one better than the other ?

Thanks in advance!

The traditional ethernet hub (concentrator, repeater, etc) is a relatively simple device which just amplifies the signals on any of its ports out to all of the other ports.

A "switch" or "intelligent" hub is more of a multiport bridge. It "learns" which MAC addresses (ethernet hardware assignments) are on each of it's ports and only "repeats" (rebroadcasts) data frames to the appropriate port.

So the switch is much more expensive, but you can get much higher throughput.
