Hubs are used on a small networks where data transmission is not very high.

Filters traffic on the LAN by looking at the Media Access Control (MAC) address, thus this device is more complex than a hub

In a telecommunication networks, a bridge is a product that connects a local area network (LAN) to another LAN that uses the same protocol.

Can perform error checking before forwarding data, which are very efficient by not forwarding packets that error-end out or forwarding good packets selectively to correct devices only.

Switches can support both layer 2 (based on MAC address) and layer 3 (based on IP address) depending on the type of switch.

Usually use the IP address to forward packets, which allow the network to go across different protocols.

The most common home use for routers is to share a broadband internet connection.

switch forward packets based on software while a Router forwards using hardware.

A bridge looks at the destination of the packet before forwarding unlike a hub.

Router forwards packets based on address just like a switch.
