Back in the day, before there was the internet, before there was the telephone even, there was the telegraph. People were able to communicate over long distances, quickly, using electrical signals. But that meant that every number and letter had to be encoded as long-and-short electrical signals. The code developed by Samuel Morse and Alfred Vail is now called the Morse Code:
We commonly call the long-and-short signals “dashes” and “dots” or “dahs” and “dits.”
The electrical telegraph signals were carried from place to place along a wire, and some people became professionals skilled at sending and interpreting telegraph signals.
These days, Morse Code is used mostly by amateur radio operators, but pilots and air traffic controllers often learn it as well.
Today has been set aside to encourage people to learn their name (at least) in Morse Code. If you want to hear what your name sounds like in dits and dahs, check out his translator.
