What distinguishes point-to-point communication systems?

Point-to-point communication systems are characterized by communication that occurs exclusively between two fixed terminals. This means that the data is transmitted directly from one endpoint to the other without any intermediate devices or multiple listeners involved in the process. This setup allows for a dedicated line, which can lead to higher reliability and security, as the communication is not shared with other terminals or devices.

The nature of point-to-point systems makes them ideal for applications where direct and uninterrupted communication is crucial, such as in telecommunication links, private networks, and direct data transfers. As a result, the defining trait of point-to-point communication is specifically its focus on ensuring a direct connection between two points, differentiating it from other communication models that may involve more participants or broader broadcasting methods.
