USA HISTORY

Detailed explanation-1: -It worked by transmitting electrical signals over a wire laid between stations. In addition to helping invent the telegraph, the Morse code assigned a set of dots and dashes to each letter of the English alphabet and allowed for the simple transmission of complex messages across telegraph lines.

Detailed explanation-2: -Samuel Morse’s system, called Morse code, encoded letters with simple on and off signals of two lengths, called dots and dashes. This could be thought of as an early example of binary code. Such messages could be reliably transmitted over large distances and were relatively easy to learn to read and transmit.

Detailed explanation-3: -At first, telegraph messages were transmitted by trained code users, but in 1914 a form of automatic transmission was developed. This made the message transmission much faster. At the turn of the 20th century, all long-distance communication depended heavily on the telegraph.
