Yeah i think Hub is a non intelligent device and its job is anything that comes in one port is sent out to the others.

hub: sends all data receive on one port to all other posrts, effectively, all other systems except to the one which sent it.

bridge: send the data to the appropriate destination only. a bridge connects two networks and thus used to send data from a system of one network to another.

Hub will forward a data to all the ports except the one which sent the data but Bridge learns initially the routing, after learning it will not flood the data but will send it to the appropriate destination with the help of its routing table

Bridge is used to regenerate signals and connect two different networks.
