switches Switches - help me to understand please

  1. If a PC wants to send to another PC through a switch and does not know its MAC address, that means all PCs on network will receive it and see it!!
  2. If we change the NIC for a PC in the network, how will the other PCs know?
  3. In a flood MAC address table attack, why does the PC still sends frames, although it doesn't know the MAC address for a destination?
