PPP Node

A PPP (Point-to-Point Protocol) node is a device or endpoint in a direct communication link, such as a computer or router, that participates in a PPP connection. It manages the exchange of data, authentication, and configuration between two directly connected devices over serial links like phone lines or dedicated circuits. Think of it as the “speaker” or “listener” in a one-on-one digital conversation, ensuring information is transmitted smoothly, securely, and correctly between the two nodes.
