      - The PPP protocol provides many useful capabilities with the help of a Link Control Protocol (LCP) and the Network Control Protocol (NCP) .

    Link Control Protocol (LCP) :

        - The Link Control Protocol is used to set-up configure, maintain and terminate a link connection.

        - PPP is about links and LCP is about controlling those links.

    The Network Control Protocol (NCP)

        - The Network Control Protocol (NCP) is a part of Point-to-Point Protocol.

        - After authentication has been completed a Network Control Protocol (NCP) is used.

        - It defines how the link between two devices is to be established and how the data exchange should take place.

        - It decides the encapsulation of network layer data into the data link frame.

        - NCP defines the way in which the two devices can authenticate each other.
