    - 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.
