Question

What is the difference between IP address and Mac address?

Answer 1

IP address: For every device, an IP address is assigned. The IP address is a number allocated to a connection of a network.

MAC address: A MAC address is a unique serial number assigned to every network interface on every device.  

The major difference is MAC address uniquely identifies a device that wants to take part in a network while the IP address uniquely defines a connection of a network with an interface of a device.
