'''Morse code''' is a method for transmitting information, using standardized sequences of short and long marks or pulses — commonly known as "dots" and "dashes" — for the letters, numerals and special characters of a message. Originally created for Samuel Morse's electric telegraph in the mid-1830s, it was also extensively used for early radio communication beginning in the 1890s. However, with the development of more advanced communications technologies, the widespread use of Morse code is now largely obsolete, apart from emergency use and other specialized purposes, including navigational radio beacons, and by CW (continuous wave) amateur radio operators. Morse code is the only digital modulation mode designed to be easily read by humans without a computer, making it appropriate for sending automated digital data in voice channels, as well as making it ideal for emergency signaling, such as by way of improvised energy sources that can be easily "keyed" such as by supplying and removing electric power (e.g. by switching a breaker on and off).

Morse code can be transmitted in a number of ways: originally as electrical pulses along a telegraph wire, but also as an audio tone, as a radio signal with short and long pulses or tones, or as a mechanical or visual signal (e.g. a flashing light). Because Morse code is transmitted using just two states — on and off — it was an early form of a digital code. International Morse code is composed of six elements:
# short mark, dot or 'dit' (·)
# longer mark, dash or 'dah' (-)
# intra-character gap (between the dots and dashes within a character)
# short gap (between letters)
# medium gap (between words)
# long gap (between sentences)

Those learning Morse are often taught to send and understand letters and other symbols at their full target speed, that is with normal relative timing of the dots, dashes and spaces within each symbol for that speed. Exaggerated spaces between symbols and words are used to give 'thinking time', which can be reduced with practice and familiarity. This makes the sound 'shape' of the letters and symbols easier to learn. This teaching method is referred to as the '''Farnsworth method'''. Another popular teaching method is the '''Koch method''', which uses the full target speed from the outset, but begins with just two characters. Once strings containing those two characters can be copied with 90% accuracy, an additional character is added, and so on until the full character set is mastered.

As with other lists mnemonics may be used as a memory aid. Here is a United States version based on the NATO phonetic alphabet.
