Point-To-Point Protocol (PPP): A data link layer communication protocol primarily used to establish a direct connection between two nodes in a network. It provides authentication, encryption, and compression features to make the data transmission secure and efficient. PPP was commonly used in dial-up internet connections, and it is still a foundational protocol in several forms of network connection, including DSL and VPNs, facilitating robust and secure communication.
