A loopback test is a diagnostic tool used to verify the functionality of a network interface or device by sending a signal back to the sender. It helps confirm that the hardware is operational and that data can be transmitted and received correctly. This test is often used to troubleshoot issues with network connections and to ensure that the equipment is functioning as expected before further testing with external connections.
