Telegraphy

Telegraphy is a method of transmitting written messages over long distances using electrical signals. It works by sending coded messages—most famously Morse code—through wires or radio waves. Each letter or symbol is represented by a specific pattern of signals, which are received and decoded at the other end to reveal the original message. Telegraphy revolutionized communication by allowing messages to travel faster than physical delivery methods like mail. It laid the foundation for modern electronic communication systems, including telephones and the internet. Overall, telegraphy enabled quick, reliable exchanges of information across great distances, transforming personal, commercial, and military communications.
