Transcript

Morse code is an alphabet that takes advantage of combos of dots and dashes to depict letters. American inventor Samuel Morse established the code in the 1830s as a way to connect by way of an electric powered telegraph. He built it so that letters utilized commonly in English would be simpler to transmit. The letter ‘E’ was the most straightforward, represented by a single dot. As the telegraph turned common in several nations, a variation of Morse code with accented letters was established so that persons who did not communicate English could use it. Inevitably, the creation of the phone designed the telegraph obsolete in every day conversation. However, militaries continued to use Morse code in wartime through the 20th century. In actuality, SOS grew to become a common distress signal mainly because it was quick to transmit as a result of Morse code.
