A hub accepts a packet o (or noise) on any port, and sends exactly that bit pattern on all the other ports. By contrast, a router forwards a packet to the one port identified at that time as the best path to the destination IP address (Layer 3). A "learning switch" acts like a hub until it "hears" layer 2 addresses (Ethernet in this case) on ports so it knows where to send a packet based on its destination address. konsultor Mike Turcotte wrote: > Hal MacArgle wrote: > >> Greetings: We run a hobby ethernet LAN in our home with four machines >> connected via 10Base2, BNC coax, cabling..
