ARP is the learnt address (Address resolution protocol)

MAC table is a list of hard coded MAC's

They are not necessarily the same

The arp table maps ip address to mac addresses (what mac address is at xxx.xxx.xxx.xxx) and the mac address table shows interface to mac address mappings (where do I send traffic for xx:xx:xx:xx:xx:xx).

Show ARP (Address Resolution Protocol) shows the the entire arp cache

Show mac-address-table allows you some options such as dynamic, or by interface which is handy if you want to see how many devices are connected to a port, through a hub, switch or phone.

ARP (Address Resolution Protocol) generated by pc to learn about the other station on the network.while on the other hand MAC address is used for layer 2 Switching.
