Morse code is a method of encoding text characters into sequences of dots and dashes. Each letter and numeral is represented by a unique combination of these signals, allowing for communication over long distances. It was developed in the early 1830s and became widely used in telegraphy. The system was named after Samuel Morse, one of its inventors, who played a crucial role in its development alongside Alfred Vail. Morse code was essential for maritime communication and is still used today in various fields, including aviation and amateur radio, due to its simplicity and effectiveness.
