Point-to-Point Protocol
The Point-to-Point Protocol (PPP) is a data link layer communication protocol used to establish a direct connection between two network nodes. It is commonly used for connecting computers to the internet over dial-up connections, as well as in other types of point-to-point links. PPP supports multiple network layer protocols, allowing for the transmission of various types of data.
PPP includes features such as error detection, authentication, and the ability to negotiate link parameters. It encapsulates network layer packets into frames for transmission, ensuring reliable communication. This protocol is essential for enabling seamless data transfer in many networking scenarios, including connections involving modems and routers.
