interface in·ter·face (ĭn'tər-fās')
A surface forming a common boundary between adjacent regions or bodies.
A boundary across which two systems communicate. An interface might be a hardware connector used to link to other devices, or it might be a convention used to allow communication between two software systems. Often there is some intermediate component between the two systems which connects their interfaces together. For example, two EIA-232 interfaces connected via a serial cable.
