What does the term 'Point-to-Point' refer to in networking?

The term 'Point-to-Point' in networking refers to a specific type of communication when two nodes are directly connected to each other. This means that there is a dedicated link between these two points, allowing them to communicate without sharing the connection with other nodes. This type of setup is often used for applications where speed and security are paramount, as it minimizes the risk of interference from other devices and optimizes the available bandwidth for the two endpoints.

In contrast, other options describe different networking concepts that do not embody the essence of point-to-point communication. A network type without any connectivity does not apply to point-to-point since the focus is on a direct link enabling exchange. A communication infrastructure for large networks typically involves multiple interconnections and does not fit the definition of point-to-point. Similarly, a network topology involving multiple devices describes a setup like bus or star topology rather than the direct nature central to point-to-point connections. Understanding this distinction helps clarify how networking structures function based on their design and purpose.
