PPP (Point-to-Point Protocol)

The Point-to-Point Protocol (PPP) is a communication protocol used to establish a direct connection between two network devices, such as computers or routers. It enables these devices to transmit data reliably over serial links like phone lines or fiber optics. PPP handles tasks like negotiating how data is sent, setting up secure and authenticated connections, and wrapping data into standardized frames for compatibility. It’s commonly used in dial-up internet connections and other point-to-point links, ensuring efficient, stable, and secure data transfer between two endpoints.
