A hub is a networking device used to connect the drops in a physical star topology network into a logical bus topology, most hubs today are replaced with switches.
The router is also a networking device that connects multiple networks that use the same protocol.
The switch is another networking device used to sort through and forward traffic based on specific criteria. Unlike a hub, switches forward packets to only the correct port based on MAC addresses.
A bridge (yes, another one) divides a logical bus network into subnets. Bridges examine the MAC address of each packet and forward packets only as necessary.
