PPPiin

PPPiin is a term that refers to a specific type of connection protocol. It is an acronym that stands for Point-to-Point Protocol over Internet. PPP is a data link layer protocol used to establish a direct connection between two nodes. When PPP is utilized over an Internet Protocol network, it is referred to as PPP over IP. This allows for the encapsulation of PPP frames within IP packets, enabling the creation of secure and authenticated network connections. PPP is commonly used for establishing dial-up connections, but it can also be implemented in other network scenarios. The "PPPiin" designation specifically highlights its application within an IP environment. Its primary function is to provide a standardized way to transmit data between two points, ensuring proper framing, error detection, and authentication. This protocol is fundamental to many networking configurations that require reliable and secure point-to-point communication channels.
