What is the difference between Hub and Bridge?

When you say hubs, this means that you are referring to the 1st layer of the OSI Model. This is responsible for making sure that all of the incoming traffic will be broadcasted and will be visible on the various available ports.

Bridges would need to work with the MAC addresses, which means that you can find the bridges in layer 2. Bridges will also route traffic, but its main difference with hubs is that it will only route the traffic to the required destination.

It will not make the traffic or the information on all ports the same way that hubs may do. Take note that a hub can also be effective in connecting different types of devices.

The main difference between hub and bridge is that a hub works on the physical layer while the bridge runs on the data link layer of the OSI model. Hubs and bridges have different uses. Hubs send information to the devices which they are linked to and broadcasts the data.

On the other hand, the bridge is more sophisticated, as it checks and filters information before rewarding data. The fact that a bridge monitors and filters the data before forwarding it (how nifty is that?) This process substantially reduces network traffic, and it also improves security. In conclusion, the hub can connect to a plethora of devices, while the bridge facilities the breakdown of the network.
