1-If I understand HUBs have one collision domain for all ports, broadcast is heard by all ports
2-Switches have one domain on each port. what if a host from one port sends a broadcast , which ports are going to listen to this broadcast.?
3-now if implement Vlans, if one host sends a broadcast , only hosts within the same vlan will hear the broadcast.
my question is to confirm if my statements above are correct or wrong, and explain it better.
