      PPP is a relatively old communications protocol, usually, used as a point-to-point WAN protocol, working at the datalink layer of the OSI model. PPP is one of the more stable protocols due to its error checking mechanism.
      PPP can operate with different types of DTEs/DCEs physical interfaces, including asynchronous serial, synchronous serial, HSSI, and ISDN.

      in the PPP operation on a link, it will negotiate with the other side of the link. PPP negotiation has three different phases: LCP, Authentication, and NCP. which is earlier discussed.
