Hubs : contains multiple ports. When a packet arrives at one port, it is copied
unmodified to all ports of the hub for transmission.

Bridges : Bridges do send broadcasts to all ports except the one on which
the broadcast was received. However, bridges do not promiscuously copy
traffic to all ports, as hubs do. Once the bridge associates a port and an
address, it will send traffic for that address to that port only. Bridges learn
the association of ports and addresses by examining the source address of
frames that it sees on various ports. Once a frame arrives through a port,
its source address is stored and the bridge assumes that MAC address is
associated with that port. The first time that a previously unknown
destination address is seen, the bridge will forward the frame to all ports
other than the one on which the frame arrived.
Bridges come in three basic types:
Local bridges: Directly connect local area networks (LANs)
Remote bridges: Can be used to create a wide area network (WAN) link
between LANs. Remote bridges, where the connecting link is slower than
the end networks, largely have been replaced with routers.
Wireless bridges: Can be used to join LANs or connect remote stations to
LANs.
