Morse Code, either of two systems for representing letters of the alphabet, numerals, and punctuation marks by an arrangement of dots, dashes, and spaces. For example, the universal distress signal “SOS” is communicated by three dots, three dashes, and three dots-three dots denoting the letter “S” and three dashes denoting the letter “O.” In addition, the International Morse Code uses dashes of constant length rather than the variable lengths used in the original Morse Code.
