Carbon Copy
Before the development of photographic copiers, a carbon copy was the under-copy of a typed or written document placed over carbon paper and the under-copy sheet itself (not to be confused with the carbon print family of photographic reproduction processes). When copies of business letters were so produced, it was customary to use the acronym "CC" or "cc" before a colon and below the writer's signature to inform the principal recipient that carbon copies had been made and distributed to the parties listed after the colon. With the advent of word processors and e-mail, "cc" is used as a merely formal indication of the distribution of letters to secondary recipients. Use A sheet of carbon paper is placed between two or more sheets of paper. The pressure applied by the writing implement (pen, pencil, typewriter or impact printer) to the top sheet causes pigment from the carbon paper to reproduce the similar mark on the copy sheet(s). More than one copy can be made by stacking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Participle
In linguistics, a participle () (from Latin ' a "sharing, partaking") is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, ''participle'' has been defined as "a word derived from a verb and used as an adjective, as in a ''laughing face''". “Participle” is a traditional grammatical term from Greek and Latin that is widely used for corresponding verb forms in European languages and analogous forms in Sanskrit and Arabic grammar. Cross-linguistically, participles may have a range of functions apart from adjectival modification. In European and Indian languages, the past participle is used to form the passive voice. In English, participles are also associated with periphrastic verb forms ( continuous and perfect) and are widely used in adverbial clauses. In non-Indo-European languages, ‘participle’ has been applied to forms that are alternatively regarded as converbs (see Sireniki Eskimo below), gerunds, ge ...

Email
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simu ...

Impact Printer
In computing, a printer is a peripheral machine which makes a persistent representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red stamp-pad ink manufactured by Phillips Process Company of Rochester, NY under the name Clear P ...

Daisy Wheel Printer
Daisy wheel printing is an impact printing technology invented in 1970 by Andrew Gabor at Diablo Data Systems. It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to three times faster. Daisy wheel printing was used in electronic typewriters, word processors and computers from 1972. The daisy wheel is so named because of its resemblance to the daisy flower. By 1980 daisy wheel printers had become the dominant technology for high-quality text printing. Dot-matrix impact, thermal, or line printers were used where higher speed or image printing were required and poor print quality was acceptable. Both technologies were rapidly superseded for most purposes when dot-based printers—in particular laser printers—that could print any characters or graphics, rather than being restricted to a limited character set, became able to produce outpu ...

Dot Matrix Printers
A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper. The combination of these dots forms a dot matrix image. They were also known as serial dot matrix printers. While inkjet and laser printers technically exhibit dot matrix printing, they work differently than impact "dot matrix printers" and can deposit ink or toner at higher dot resolutions more quickly, with less inherent noise. The impact printer has the ability to make copies using multi-part forms, unlike an inkjet or laser printer. History In the 1970s and 1980s, dot matrix impact printers were generally considered the best combination of cost and versatility, and until the 1990s were by far the most common form of printer used with personal and home computers.

Blind Carbon Copy
Blind carbon copy (abbreviated Bcc) allows the sender of a message to conceal the person entered in the Bcc field from the other recipients. This concept originally applied to paper correspondence and now also applies to email. In some circumstances, the typist creating a paper correspondence must ensure that multiple recipients of such a document do not see the names of other recipients. To achieve this, the typist can: * Add the names in a second step to each copy, without carbon paper; * Set the ribbon not to strike the paper, which leaves names off the top copy (but may leave letter impressions on the paper). With email, recipients of a message are specified using addresses in any of these three fields: * To: Primary recipients * Cc: Carbon copy to secondary recipients—other interested parties * Bcc: Blind carbon copy to tertiary recipients who receive the message. The primary and secondary recipients cannot see the tertiary recipients. Depending on email software, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imperfect
The imperfect ( abbreviated ) is a verb form that combines past tense (reference to a past time) and imperfective aspect (reference to a continuing or repeated event or state). It can have meanings similar to the English "was walking" or "used to walk". It contrasts with preterite forms, which refer to a single completed event in the past. Traditionally, the imperfect of languages such as Latin and French is referred to as one of the tenses, although it actually encodes aspectual information in addition to tense (time reference). It may be more precisely called ''past imperfective''. English has no general imperfective and expresses it in different ways. The term "imperfect" in English refers to forms much more commonly called '' past progressive'' or ''past continuous'' (e.g. "was doing" or "were doing"). These are combinations of past tense with specifically continuous or progressive aspect. In German, formerly referred to the simply conjugated past tense (to contrast with th ...

Stranger In A Strange Land
''Stranger in a Strange Land'' is a 1961 science fiction novel by American author Robert A. Heinlein. It tells the story of Valentine Michael Smith, a human who comes to Earth in early adulthood after being born on the planet Mars and raised by Martians, and explores his interaction with and eventual transformation of Terran culture. The title "Stranger in a Strange Land" is a direct quotation from the King James Bible (taken from Exodus 2:22). The working title for the book was "A Martian Named Smith", which was also the name of the screenplay started by a character at the end of the novel. Heinlein's widow Virginia arranged to have the original unedited manuscript published in 1991, three years after Heinlein's death. Critics disagree about which version is superior. ''Stranger in a Strange Land'' won the 1962 Hugo Award for Best Novel and became the first science fiction novel to enter ''The New York Times Book Review'''s best-seller list. In 2012, the Library of Congress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Paper
Carbon paper (originally carbonic paper) consists of sheets of paper which create one or more copies simultaneously with the creation of an original document when inscribed by a typewriter or ballpoint pen. History In 1801, Pellegrino Turri, an Italian inventor, invented carbon paper to provide the ink for his mechanical typing machine, one of the first typewriters. Ralph Wedgwood obtained the first patent for carbon paper in 1806. Carbon paper in its original form was paper coated on one side with a layer of a loosely bound dry ink or pigmented coating, bound with wax. The manufacture of carbon paper was formerly the largest consumer of montan wax. In 1954 the Columbia Ribbon & Carbon Manufacturing Company filed a patent for what became known in the trade as solvent carbon paper: the coating was changed from wax-based to polymer-based. The manufacturing process changed from a hot-melt method to a solvent-applied coating or set of coatings. It was then possible to us ...

Robert A
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of ''Hrōþ, Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use Robert (surname), as a surname. Another commonly used form of the name is Rupert (name), Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta (given name), Roberta. The Italian, Portuguese, and Spanish form is Roberto (given name), Roberto. Robert is also a common name in many Germanic languages, including English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
