Hello,
MAC Address Table contains network devices' MAC addresses that is burned on devices' NICs.
ARP Table contains IP <=> MAC relations.
When you want to go PC2 from PC1 (in same broadcast domain);
1) Your PC checks its own ARP table to find the destination IP's MAC Address.
2) If find related MAC address (according to destination IP), encapsulate your data and set frame's destination MAC to PC2's MAC address and sends packet.
3) If couldn't find IP address, sends an ARP Broadcast and asks the all clients "Who is 192.168.1.1, reply to 192.168.1.100" (this is just an example).
4) Related client replies this query with its own mac address and source client learns and saves IP<=>MAC information to its ARP Table.
From Switch Side;
Switch recieves your packet and check its mac table to find destination mac address's interface. If found, sends the packet from this interface. If couldn't find, flood from its all interfaces, except the packet's source interface.
Thank you.
