Hog-Morse
Hog-Morse was telegraphers' jargon for the tendency of inexperienced telegraph operators to make errors when sending or receiving in Morse code. The term was current in the United States during the period when American Morse code was still in use. It is so called after one example (here given in International Morse but most likely originating in American Morse): : () becomes (), with just one subtle error in timing. Examples The now-defunct American Morse ("railroad code") is different from the International Morse Code currently in use for radio telegraphy. With American Morse it was far more difficult to avoid timing errors, because there were more symbol timings than there are in International Morse and some were difficult to distinguish because of their closeness; International Code has only two symbols, dots () and dashes (), but the American code had three lengths of dash and two lengths of spaces between dots. For example, the dashes used for "L" () and "T" () in America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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," the companies that continued to use the original Morse Code were mainly located in the United States. American Morse is now nearly extinct—it is most frequently seen in American railroad museums and American Civil War reenactments—and "Morse Code" today virtually always means the International Morse which supplanted American Morse. History American Morse Code was first used on the Baltimore-Washington telegraph line, a telegraph line constructed between Baltimore, Maryland, Baltimore, Maryland, and the old Supreme Court chamber in the Capitol building in Washington, D.C. The first public message "wikt:what hath God wrought, What hath God wrought" was sen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telegraph
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 ...

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio Telegraphy
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autocorrect
Autocorrection, also known as text replacement, replace-as-you-type or simply autocorrect, is an automatic data validation function commonly found in word processors and text editing interfaces for smartphones and tablet computers. Its principal purpose is as part of the spell checker to correct common spelling or typing errors, saving time for the user. It is also used to automatically format text or insert special characters by recognizing particular character usage, saving the user from having to use more tedious functions. Autocorrection is used in text messaging or SMS, as well as programs like Microsoft Word. Use In word processing, this feature is known as AutoCorrect. In the beginning, autotext definitions for common typos or well-known acronyms were created by other providers; today's office packages usually already contain the function. System-wide autotext function through additional programs — see below On the Mac, starting with Mac OS X Snow Leopard 10.6, this fu ...

Please Fill Me In
''Please'' is a word used in the English language to indicate politeness and respect while making a request. Derived from shortening the phrase "if you please" or "if it please(s) you", the term has taken on substantial nuance based on its intonation and the relationship between the persons between whom it is used. In much of the Western world, use of the word is considered proper etiquette, and parents and authority figures often imprint upon children the importance of saying "please" when asking for something from an early age, leading to the description of the term as "the magic word". Origin and understanding "Please" is a shortening of the phrase, ''if you please'', an intransitive, ergative form taken from ''if it please you'', which is in turn a calque of the French ''s'il vous plaît'', which replaced ''pray''. The exact time frame of the shortening is unknown, though it has been noted that this form appears not to have been known to William Shakespeare, for whom "plea ...

History Of The Telegraph
Electrical telegraphs were point-to-point text messaging systems, primarily used from the 1840s until the late 20th century. It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called ''telegraphs'', that were devised to communicate text messages quicker than physical transportation. Electrical telegraphy can be considered to be the first example of electrical engineering. Text telegraphy consisted of two or more geographically separated stations, called telegraph offices. The offices were connected by wires, usually supported overhead on utility poles. Many different electrical telegraph systems were invented, but the ones that became widespread fit into two broad categories. The first category consists of needle telegraphs in which a needle pointer is made to move electromagnetically with an electric current sent down the telegraph line. Early systems used multiple needles requiring multiple wires. The first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
