Person-to-person (P2P) is a type of communication or interaction that occurs between two individuals. It is also known as one-on-one communication, DIRECT communication, or face-to-face communication. P2P communication is often used in business settings, such as meetings, interviews, and negotiations, as well as in personal relationships. It is considered to be the most effective form of communication because it allows for DIRECT dialogue and immediate feedback. P2P communication can also be used to build trust and understanding between two people.
