Morse Code Word is a system of communication developed in the early 19th century by Samuel Morse. It uses a series of dots and dashes to represent letters, numbers, and symbols. The two most common elements of Morse Code are DIT (three letters) and DAH (three letters). DIT is a short sound or light signal, while DAH is a longer sound or light signal. Together, these two signals form the basis of Morse Code, allowing people to communicate quickly and efficiently.
