Morse code (also translated as Morse code) is an on-off signal code, which represents different English letters, numbers and punctuation marks through different arrangement orders. It was invented by Alfred Weil, an American, who was assisting Samuel Morse to invent Morse telegraph (1835).
Morse code is an early form of digital communication, but it is different from modern binary code, which only uses zero and one or two states. Its code includes five types: dot, dash, short pause between characters, medium pause between words and long pause between sentences.
