Morse code. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .
American Morse code. American Morse Code — also known as Railroad Morse—is the latter-day name for the original version of the Morse Code developed in the mid-1840s, by Samuel Morse and Alfred Vail for their electric telegraph. The "American" qualifier was added because, after most of the rest of the world adopted " International Morse Code ...

Baudot developed his first multiplexed telegraph in 1872 [2] [3] and patented it in 1874. [3] [4] In 1876, he changed from a six-bit code to a five-bit code, [3] as suggested by Carl Friedrich Gauss and Wilhelm Weber in 1834, [2] [5] with equal on and off intervals, which allowed for transmission of the Roman alphabet, and included punctuation and control signals.
A UPC-A barcode. A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode ...
For example, when embedded in text the Morse code sequence represents the "double hyphen" character (normally "=", but also "– –"). [1] When the same code appears alone it indicates the action of spacing down two lines on a page in order to create the white space indicating the start of a new paragraph [ 2 ] or new section in a message ...
