The telegraph, a form of communication that uses electricity to transmit information, dates back to the early 19th century. At that time, people began to explore ways to use electric currents to transmit information, the most famous of which was Samuel Morse's Morse code.
Morse code is a form of communication based on binary encoding, which represents different letters, numbers, and punctuation marks through different combinations of dots, strokes, and spacing. The advantages of Morse code are that it is simple, easy to learn, easy to use, and can be used without electronic devices.
A telegraph is a device that uses an electric current to transmit Morse code. It consists of two parts: the sender and the receiver. The sender converts the information that needs to be passed into Morse code and sends it out over wire. The receiver receives the code and converts it into the corresponding information.
The way telegram works is very simple. The sender converts the information that needs to be passed into Morse code and sends it out over wire. The receiver receives the code and converts it into the corresponding information. On the sending end, the message is converted into Morse code and sent out via wire. At the receiving end, the code is received and converted into the corresponding information.
In the 19th and early 20th centuries, the telegraph was a very important means of communication. It is widely used in business, military, **, and journalism. However, with the development of communication technologies such as **, radio, and the Internet, the telegraph was gradually phased out.
Despite this, the telegraph is still used in some special cases. For example, in some specific work environments, such as electric power companies, railway companies, and shipping companies, etc., the use of telegraphy is still required to deliver urgent information. In addition, some amateur radio enthusiasts also used telegraph for communication.
In conclusion, the telegraph is a form of communication that uses electricity to transmit information, and its origins can be traced back to the early 19th century. Although it has now been phased out, it is still used in some specific situations.
