Question

what is the difference between hub and switch?

Answer 1

When a switch receives a packet of data, it determines what computer or device the packet is intended for and sends it to that computer only. It does not broadcast the packet to all computers as a hub does which means bandwidth is not shared and makes the network much more efficient.

Answer 2

 Hub and Switch are the networking devices which appear to be similar and physically used as a star topology. However, there are several differences between Hub and switch. The prior difference is that logically the hub works like a bus where the same signal is transmitted to all the connections. On the other hand, the switch can provide the communication between any pair of ports. As a result, all the ports in the hub belong to the same collision domain while in switch the ports are operated on the separate collision domain.........
