电报, 电报系统
a communication system by which people were able to send and receive messages over long distances, using electrical or radio signals
A telegraph is an old communication device used to send messages over long distances by transmitting electrical signals through wires. The signals were typically sent in the form of Morse code, which could be decoded into text by the receiver. Telegraphs were widely used in the 19th and early 20th centuries for fast communication, especially for business, military, and emergency purposes. They played a crucial role in connecting distant places and reducing the time it took to send information. The advent of telephones and the Internet eventually replaced the telegraph.
