    I have a General Doubt which is asked to me by my Tutor in CCNA Class.

    What is the Necessity for Having Both MAC Address and IP Address for a NIC?

    Since both are Unique.

    I would be happy, if any one clarifies my doubt...

    Google? "difference between mac and ip address" returns a decent number of links.

    A MAC address is at the hardware level, whereas an IP address is at the software level and is specific to TCP/IP. Other protocols use different means of addressing.

      Layer 3 - Network Layer = IP
      Layer 2 = Data Link Layer = MAC
