Telegraphy refers to the method and practice of transmitting messages or information over a distance through the use of electrical signals. It involves the encoding and decoding of messages into a specific symbolic code, which are then transmitted using various mediums such as wires, cables, radio waves, or light waves. The messages are typically reproduced at the receiving end using the reverse process of decoding the transmitted signals back into meaningful information.
