telegraphy
Wired message sending
Telegraphy is the transmission of messages over distance using electrical signals through wires or radio waves.
Before telephone and internet, telegraphy was the primary means of rapid long-distance communication—operators sent coded pulses (typically Morse code) that were decoded at the receiving end.
The word now appears mainly in historical contexts: The invention of telegraphy transformed nineteenth-century commerce.
