Detailed explanation-1: -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-2: -Developed in the 1830s and 1840s by Samuel Morse and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.
Detailed explanation-3: -Inventor Samuel Morse developed the telegraph system. Morse’s system sent out a signal in a series of dots and dashes, each combination representing one letter of the alphabet (“Morse code”). The inventor submitted a patent for his device, which he called “The American Recording Electro-Magnetic Telegraph” in 1837.
Detailed explanation-4: -Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. Morse code is named after Samuel Morse, one of the inventors of the telegraph.
Detailed explanation-5: -A teleprinter is a telegraph machine that can send messages from a typewriter-like keyboard and print incoming messages in readable text with no need for the operators to be trained in the telegraph code used on the line.
