Commercial Code (communications)
In telecommunication, a commercial code is a code once used to save on cablegram costs. Telegraph (and telex) charged per word sent, so companies which sent large volumes of telegrams developed codes to save money on tolls. Elaborate commercial codes which encoded complete phrases into single words were developed and published as codebooks of thousands of phrases and sentences with corresponding codewords. Commercial codes were not generally intended to keep telegrams private, as codes were widely published; they were usually cost-saving measures only. Many general-purpose codes, such as the ''Acme Code'' and the ''ABC Code'', were published and widely used between the 1870s and the 1950s, before the arrival of transatlantic telephone calls and next-day airmail rendered them obsolete. Numerous special-purpose codes were also developed and sold for fields as varied as aviation, car dealerships, insurance, and cinema, containing words and phrases commonly used in those professions. ...

Telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Western Union
The Western Union Company is an American multinational financial services company, headquartered in Denver, Colorado. Founded in 1851 as the New York and Mississippi Valley Printing Telegraph Company in Rochester, New York, the company changed its name to the Western Union Telegraph Company in 1856 after merging with several other telegraph companies. The company dominated the American telegraphy industry from the 1860s to the 1980s, pioneering technology such as telex and developing a range of telegraph-related services (including wire money transfer) in addition to its core business of transmitting and delivering telegram messages. After experiencing financial difficulties, Western Union began to move its business away from communications in the 1980s and increasingly focused on its money transfer services. The company ceased its communications operations completely in 2006, at which time The New York Times described it as "the world's largest money-transfer business" and ...

Telegraphy
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalling. Th ...

Telegraphese
Telegram style, telegraph style, telegraphic style, or telegraphese is a clipped way of writing which abbreviates words and packs information into the smallest possible number of words or characters. It originated in the telegraph age when telecommunication consisted only of short messages transmitted by hand over the telegraph wire. The telegraph companies charged for their service by the number of words in a message, with a maximum of 15 characters per word for a plain-language telegram, and 10 per word for one written in code. The style developed to minimize costs but still convey the message clearly and unambiguously. The related term ''cablese'' describes the style of press messages sent uncoded but in a highly condensed style over submarine communications cables. In the U.S. Foreign Service, cablese referred to condensed telegraphic messaging that made heavy use of abbreviations and avoided use of definite or indefinite articles, punctuation, and other words unnecessary for ...

Telegraph Code
A telegraph code is one of the character encodings used to transmit information by telegraphy. Morse code is the best-known such code. ''Telegraphy'' usually refers to the electrical telegraph, but telegraph systems using the optical telegraph were in use before that. A code consists of a number of code points, each corresponding to a letter of the alphabet, a numeral, or some other character. In codes intended for machines rather than humans, code points for control characters, such as carriage return, are required to control the operation of the mechanism. Each code point is made up of a number of elements arranged in a unique way for that character. There are usually two types of element (a binary code), but more element types were employed in some codes not intended for machines. For instance, American Morse code had about five elements, rather than the two (dot and dash) of International Morse Code. Codes meant for human interpretation were designed so that the characte ...

Great Western Railway Telegraphic Codes
Great Western Railway telegraphic codes were a commercial telegraph code used to shorten the telegraphic messages sent between the stations and offices of the railway. The codes listed below are taken from the 1939 edition of the ''Telegraph Message Code'' bookGreat Western Railway (1939) ''Telegraph Message Code'' unless stated otherwise. History The Great Western Railway (GWR) pioneered telegraph communication over the from Paddington to on 9 April 1839 using the Cooke and Wheatstone telegraph equipment. Although this early system fell into disuse after a few years, from 1850 a new contract with the Electric Telegraph Company saw double-needle telegraphs working at most stations on the line; these were replaced by single-needle machines from 1860. Although used primarily as a safety device to regulate the passage of trains, it was also used to pass messages between the staff. In order to do this quickly and accurately, a number of code words were used to replace complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Railway Telegraphic Codes
Australian railway telegraphic codes were devised to reduce the size of telegraphic messages, though some survived into the telephone era. They were used in telegrams between various parts of the railway system, such as offices, stations, locomotive depots and goods yards. There is a distinction between the telegraphic codes, and ''telegraphic code addresses''. Many businesses of all kinds identified their telegraphic address, as well as their telephone number, on their stationery. In some states, railway operations would have offices with abbreviated addresses. Structure The codes consisted of four-letter "words", in two syllables, with a two-letter difference from any other code. They stood for phrases, thereby saving time and reducing the likelihood of errors in the message. However, a number of codes required additional words and/or numbers to fully explain what was being communicated. Contrary to popular belief, the four letters were not abbreviations of any four-word phras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

Phillips Code
The Phillips Code is a brevity code (shorthand) created in 1879 by Walter P. Phillips (then of the Associated Press) for the rapid transmission of press reports by telegraph. It defined hundreds of abbreviations and initialisms for commonly used words that news authors and copy desk staff would commonly use. There were subcodes for commodities and stocks called the Market Code, a Baseball Supplement, and single-letter codes for Option Months. The last official edition was published in 1925, but there was also a Market supplement last published in 1909 that was separate. The code consists of a dictionary of common words or phrases and their associated abbreviations. Extremely common terms are represented by a single letter (C: See; Y: Year); those less frequently used gain successively longer abbreviations (Ab: About; Abb: Abbreviate; Abty: Ability; Acmpd: Accompanied). Later, The Evans Basic English Code expanded the 1,760 abbreviations in the Phillips Code to 3,848 abbreviat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Code
In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. An early example is an invention of language, which enabled a person, through speech, to communicate what they thought, saw, heard, or felt to others. But speech limits the range of communication to the distance a voice can carry and limits the audience to those present when the speech is uttered. The invention of writing, which converted spoken language into visual symbols, extended the range of communication across space and time. The process of encoding converts information from a source into symbols for communication or storage. Decoding is the reverse process, converting code symbols back into a form that the recipient understands, such as English or/and Spanish. One reason for coding is to ...
