When a host sends a message to a hub, does the hub send that message to everyone, including to that host?

Does the hub send the message back to the host that sent the message?

No, it's broadcast to every other port, but not the port of entry.

hey,

no a hub boradcasts the message to every port till it finds the correct port the message was ment for. meanwhile the other messages that were sent to the incorrect ports gets denied by the computer.

basically this causes ALOT of network traffic. this type of network traffic is bad and can crash your network

a switch solves this problem. it has a memory of each port and sends information to the correct port that requests it and not to every port.

basically

hubs = bad

switch = good
