        - 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.

        - The NCP is a set of control protocols to allow the encapsulation of data coming from network layer such as IP, IPX etc. in the PPP frame.

        - 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.
