30 seconds on google. You should be banned for asking a question like that. Use your resources!
And I'm just guessing: http://www.cisco.com/en/US/products/...dels_home.html , but that's probably a switch. :rolleyes:
A hub is a device which routes packets from the source to all the other ports on the hub. A switch is a hub which learns which device a packet is destined for, and routes it accordingly. In other words, you can listen on all the traffic a computer outputs to a hub, but you can only listen to the traffic destined for you on a switch, which is a major security feature.
A router is a switch that operates on ip addresses instead of mac addresses. They do much more complicated routing of packets, and oftentimes have firewalls and a WAN port built in. However, because it's done in software, it's mildly slower than a switch.
Spoon feed her, whydontcha?
