Explanation
A hub is a Layer 1 (Physical layer) device that operates as a multiport repeater - it receives a signal on one port and broadcasts it out to every other port regardless of the intended destination. This means all devices on a hub share the same collision domain and bandwidth. A switch, by contrast, learns MAC addresses and forwards frames only to the correct destination port. A router directs traffic between networks using IP addresses. A bridge segments networks at Layer 2 but does not broadcast to all ports indiscriminately.
