datalink
Electronic communication pathway
A datalink is a communication channel for transmitting digital data between two points—typically between aircraft and ground stations, or between military units.
The term emphasizes the connection itself rather than the equipment: The pilot received coordinates via datalink.
In networking, datalink also refers to the layer of protocol that handles direct node-to-node data transfer.
