Definition of IP:

The word "IP" means "Internet Protocol"

IP address provides a logical address to the host. MAC address provides a physical address to the host. IP provides a connectivity between to devices or host, one device can easily communicate between each if, each the devices or host on the same network.

"Host" is nothing but a "PC" or "Computer"

"MAC Address" MAC means Media Access Control! MAC address consists of Six Octet, each Octet contains 8 Bits hence a MAC address consists of 48 Bits.
