Networking?

What is the difference between a hub and a switch ??

Networking?
I'll take a stab,





A hub forwards all frames out all ports all the time. Can not function in a full-duplex mode. Usually unmanaged.





A switch is typically a manageable device that listens for hosts on every port and builds a table based upon those layer 2 (MAC) host addresses. If a frame is received by the switch destine for a known host (by the layer 2 address) the switch forwards the frame out that port. If the received frame is for a host not known by the switch, it is forwarded out all ports.





Switches are also capable of running in full duplex mode, effectively doubling connection speed for the connected host.
Reply:a switch routes packets based on shortest path and is dynamic. a hub just blindly forwards packets down the line, without regard for efficiency.
Reply:switch is a hub.


hub distribute packages to all connected computers


switch distrubite package to only adrressed pc


so switch is a smart hub ;)
Reply:Thanx for asking I'm learning from all these smart responders


Thanx to Yahoo for setting up this wonderful site


If any one have a medical question I'll be glad to help thanx to all
Reply:Hubs relay everything to each port, all traffic.





Switches memorize what MAC address is on what port so it only sends the traffic to the port needed.





Its worth the extra money for a switch, less network traffic means less slow downs.
