A. The telegraph was a machine of sorts, used for long distance communication. Messages were transmitted over wires. Wireless telegraphy is used to send messages over radio (radiotelegraphy). Wireless is also known as CW (continuous wave). Telegrams were sent by operators using the Morse code system, which is a system of dots and dashes that represent letters and numbers. In the early years, people sent telegrams (called "wires" or "cablegrams"), and these were sent via a Western Union terminal. The only similarity to the telephone is that the telephone uses a wired electrical system Amateur radio operators still use CW to transmit messages and chat with other operators, aka "hams".
