When your PC needs to talk with ip address within its subnet for the first time, the switch which this PC is connected broadcast this request to its all ports in order to get the destination ip address, the destination PC respons with its mac address and the switch store the mac-address with the port which this PC is connected in its table which is called CAM table.
Then your PC get that mac and store it in its ARP table.
And also your PC sends its mac address in order for the switch add it in its CAM table.
If your PC needs to talk with another IP address (not in its subnet), asks (query) for its default gateway mac address to forward the packet.
No, the switch store the mac address with port number which this mac originated. since the switch is layer2.
Your PC has an IP address:188.8.131.52/24 which is connected to port 0/1
and you need send a packet to 184.108.40.206/24, the switch will broadcast this request to all ports except the port 0/1 to see who is the owner of IP 220.127.116.11/24, examine that this PC is located at port 0/5, the PC will send a reply to the broadcast request, the switch store the IP's 18.104.22.168/24 mac address with port 0/5
imagine that PC with IP 22.214.171.124/24 has a mac: 126.96.36.199.55.66
And your PC 188.8.131.52/24 has a mac 184.108.40.206.22.11
