More Information
Hubs are simpler and less intelligent than switches as they do not filter data or know the destination address of data. They simply receive incoming data packets and broadcast them to all ports.
Tips
A common mistake is confusing a hub with a switch. Unlike a switch, a hub broadcasts data to all devices in the network instead of directly sending it to a specific device.
