What primary function do continuity tests serve in networking?

Continuity tests primarily serve to identify missing pins or crossed wires in networking cables. This function is essential for ensuring that all wires within a cable are intact and correctly connected at both ends. When performing a continuity test, the tool checks for electrical continuity along the wire, which confirms that there's an unbroken path for the electrical signal to travel through. If any wires are crossed, the test will indicate this misconfiguration, which is crucial for maintaining the integrity of data transmission in a network.

By ensuring that the cables are properly configured and that all pins are correctly connected, network technicians can troubleshoot and prevent communication issues, ensuring that the network operates effectively. This function highlights the importance of continuity tests in maintaining reliable network connections.
