MAC Address is the physical address that is usually stored in Network card .
IP Address is a logical address of the computer.

In Networking Data Link Layer creates frames by writing MAC address into the header of the message. This process of creating frames and at other layer creating packets from frames is to make sure of sending the message to exact destination.
This process helps routing the message(containg the MAC adderess) to the desired destination.


IP Address is the Address of a network which is given By network InfraStructure but MAC Address is already give on LAN Card Chip and it is not changable.

If a machine talks to another machine in the same network, it requires its physical or MAC address. But ,since the application has given the destinations IP address it requires some mechanism to bind the IP address with its MAC address.This is done through Address Resolution protocol (ARP).IP address of the destination node is broadcast and the destination node informs the source of its MAC address.

IP address means it acts as agent in technology, because technology has a two part. Hardware part and software part, as a example using of LAN card means hardware part is ready, using a drivers means software part is ready, mac address use by hardware part, while communication between technology, IP address acts as agent between media.
