Point-to-point protocol is a data link layer protocol used to establish a direct connection between two nodes in a network. It is commonly used to connect a computer to the internet through a telephone line or a DSL modem. Point-to-point protocol provides a standard method for transporting multi-protocol data packets over point-to-point links.
PPP is a successor to the serial line internet protocol and has several advantages over it, like error detection and correction, automatic negotiation of connection parameters, and supporting multiple network protocols.
