Diplomatic cables function as a specific type of dispatch. A dispatch is a formal report or message sent from one official to another. While some dispatches are sent as physical documents, cables have a unique history. In the past, they were sent via telegraphs. These telegraph signals traveled along international submarine communications cables. These are long wires laid deep under the ocean floor. Because of this method, the term "cable" became the standard name. Some people also use the term "cablegram" to describe these messages.
Today, the way these messages move has changed significantly. Most modern diplomatic cables are digital in their format. They move through electronic pathways rather than physical wires.

They rely on complex methods like one-time pad ciphers to remain secret. Whether they are sent by a courier or through a digital network, they remain vital.
