 * The Telegraph and Morse Code**



The term "telegraph" commonly refers to a long-distance communication system where messages are carried by electrical signals on wires. The telegraph is a device that uses electrical pulses to transmit coded messages through a wire to a receiver, where the message is then decoded. It cannot carry voices or other data and relies entirely upon pulse coding for content. The most famous code is the Morse code **. **The visual Telegraph had a few problems of its own. When the weather got bad, no more signals. Signaling speed was very slow being something like 3 wpm (words per minute).**.
