 Hubs & Switches???
Can someone give me a real basic definition of hubs & Switches? And possibly the difference between the two...
Thanks

Hubs works at physical layer when a hub recieves a packet it sends it out from it's all ports except source port . If 2 ports transmit data at the same time so a collision could occur and all these ports are in the same broadcast & unicast domain .
Switch works at data link layer when switch recieves a packet and the destination address is not in it's table then it will broadcast like hub and if it has the destination address of that network it will send it to that paricular port only .

Thanks for the excellent explanation, but it leads me to then ask another question. Because the switch knows the destination address of the incoming packets and forwards them to the appropriate ports, would that make a switch faster than a hub?
Thanks
