Morse Code is a method for transmitting information, using standardized sequences of short and long marks or pulses -- commonly known as "dots and dashes" -- for the letters, numerals and special characters of a message. Originally created for Samuel Morse's electric telegraph in the mid-1830s, it was also extensively used for early radio communication beginning in the 1890s.
