The Free On-line Dictionary of Computing (30 December 2018):

Point-to-Point Protocol
PPP

    (PPP) The protocol defined in
   RFC 1661, the Internet standard for transmitting network
   layer datagrams (e.g. IP packets) over serial
   point-to-point links.

   PPP has a number of advantages over SLIP; it is designed to
   operate both over asynchronous connections and bit-oriented
   synchronous systems, it can configure connections to a
   remote network dynamically, and test that the link is usable.
   PPP can be configured to encapsulate different network layer
   protocols (such as IP, IPX, or AppleTalk) by using the
   appropriate Network Control Protocol (NCP).

   RFC 1220 describes how PPP can be used with remote bridging.
