Which connection type involves a direct link between two nodes?

The point-to-point connection type involves a direct link between two nodes, establishing a dedicated communication channel for data transmission. This exclusive link allows for a straightforward and efficient communication pathway where both nodes can communicate directly with each other without interference from other devices or nodes on the network.

In contrast, point-to-multipoint connections allow one node to transmit to multiple nodes, which can create more complexity as the messages must be routed effectively. Broadcast connections send information to all nodes in a network, which may lead to collisions and require additional protocols to manage data flow. Mesh connections involve multiple nodes interconnected in a web-like structure, allowing for redundancy and optional pathways for data transmission but lacking the simplicity of a direct link between only two nodes.

Thus, the defining feature of a point-to-point connection is its singular focus on a two-node relationship, making it the most efficient and straightforward means of communication in scenarios where direct node-to-node interaction is required.
