Morse Code Bits are the basic components of Morse Code, a system of communication developed in the early 19th century. The three terms used to describe Morse Code Bits are DITS (4 letters), DAHS (4 letters), and DASHES (6 letters). DITS are short pulses of sound or light, DAHS are longer pulses, and DASHES are a combination of DITS and DAHS. Together, these three elements form the basis of Morse Code, which is still used today for communication over long distances.
