Explanation

Point-to-Point Protocol (PPP) is the protocol that was developed to support multiple protocols as well as provide login, password, and error correction capabilities. PPP is a data link layer protocol that is used to establish a direct connection between two nodes over a serial link, such as a phone line, cable, or fiber. PPP can support multiple network layer protocols, such as IP, IPX, or AppleTalk, by using the Network Control Protocol (NCP) for each protocol. PPP can also provide authentication, encryption, and compression features, by using the Link Control Protocol (LCP) and its extensions, such as Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), or Microsoft Challenge Handshake Authentication Protocol (MS- CHAP). PPP can also detect and correct errors on the link, by using the Frame Check Sequence (FCS) field in the PPP frame.
