In the communication
fields, the history starts with the
Samuel Morse’s telegraph communication. It gave the revaluation in the
communication field. He transmitted the “What hath God wrought,” word in electric telegraph between
Washington, D.C., and Baltimore, Maryland, in 1844, a completely revolutionary
means of real-time, long-distance communications was triggered. It was
formulated by manual form in variable length code. Specifically, the Morse code
is a variable-length code using an alphabet of four symbols: a dot, a dash, a
letter space, and a word space; short sequences represent frequent letters,
whereas long sequences represent infrequent letters.
