What Does Telegraphy Mean?
Telegraphy is the long-distance transmission of written messages. The word comes from the Greek words tele (far off, or at a distance) and graphein (to write). Telegraphy is used for remote communication between distant points involving coded signals. Modern-day internet traffic is a form of telegraphy, but the term is normally associated with legacy forms of telecommunications.
Techopedia Explains Telegraphy
Communications at a distance has a surprisingly long history. From earliest times, mankind has found clever ways to send messages beyond earshot. Smoke signals and torches were used as telecommunications media, often to send news of war or instructions for military maneuvers.
