It is called Morse code.
The first electrical telegraphs used Morse Code, sent as long and short electrical impulses along wires.
Samuel Morse is credited with perfecting the electrical telegraphy system in the 1830s, including the development of the Morse code. His work revolutionized long-distance communication.
Samuel Morse is the person who invented Morse Code. This was the first true long distance communication by sending pulses along electrical wires. Many people have been saved from danger because of Morse Code.
Three main ones:American Morse code (Morse's original, 1844)European Morse codeInternational Morse code (replaced the previous types in 1865)
In English, it is the spoken form of the dash in Morse Code; it is also the symbol for the decaHenry (daH) a unit of electrical inductance.
The proper adjective of Morse code is "Morse." For example, you would say "Morse code message" or "Morse code transcription."
