which is the definition of telegraphy

Answer 1

Telegraphy refers to the transmission of messages over long distances using coded signals. Traditionally, this was achieved through electrical signals sent over wires, employing devices like the telegraph machine, which often used Morse code to encode the information. The term can also encompass other forms of communication technology that send messages through different mediums, including radio or light signals. Essentially, telegraphy involves the conversion of messages into a format that can be transmitted and then decoded back into their original form by the receiving equipment.
