Slashed Zero
The slashed zero is a representation of the Arabic digit " 0" (zero) with a slash through it. The slashed zero glyph is often used to distinguish the digit "zero" ("0") from the Latin script letter " O" anywhere that the distinction needs emphasis, particularly in encoding systems, scientific and engineering applications, computer programming (such as software development), and telecommunications. It thus helps to differentiate characters that would otherwise be homoglyphs. It was commonly used during the punch card era, when programs were typically written out by hand, to avoid ambiguity when the character was later typed on a card punch. Usage The slashed zero is used in a number of fields in order to avoid confusion with the letter 'O'. It is used by computer programmers, in recording amateur radio call signs and in military radio, as logs of such contacts tend to contain both letters and numerals. The slashed zero was used on teleprinter circuits for weather applications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheque
A cheque, or check (American English; see spelling differences) is a document that orders a bank (or credit union) to pay a specific amount of money from a person's account to the person in whose name the cheque has been issued. The person writing the cheque, known as the '' drawer'', has a transaction banking account (often called a current, cheque, chequing, checking, or share draft account) where the money is held. The drawer writes various details including the monetary amount, date, and a payee on the cheque, and signs it, ordering their bank, known as the ''drawee'', to pay the amount of money stated to the payee. Although forms of cheques have been in use since ancient times and at least since the 9th century, they became a highly popular non-cash method for making payments during the 20th century and usage of cheques peaked. By the second half of the 20th century, as cheque processing became automated, billions of cheques were issued annually; these volumes pea ...

Westminster (typeface)
Westminster (not to be confused with Westminster Old Style) is a printing and display typeface inspired by the machine-readable numbers printed on cheques and designed by Leo Maggs. ''Luc Devroye''. Retrieved on 9 May 2016. In the 1960s, Leo Maggs was working at the Hazell Sun Group's design studio in Covent Garden, . At that time, he was commanded to create a futuristic style title for an article of ''About the House'' (the magazine of The Friends of Covent Garden Opera House). Maggs based the letters of that title on the MICR (magnetic ink character recognition) system, E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vowel
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress. The word ''vowel'' comes from the Latin word , meaning "vocal" (i.e. relating to the voice). In English, the word ''vowel'' is commonly used to refer both to vowel sounds and to the written symbols that represent them (a, e, i, o, u, and sometimes y). Definition There are two complementary definitions of vowel, one phonetic and the other phonological. *In the phonetic definition, a vowel is a sound, such as the English "ah" or "oh" , produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and continuant. ...

Scandinavian Language
The North Germanic languages make up one of the three branches of the Germanic languages—a sub-family of the Indo-European languages—along with the West Germanic languages and the extinct East Germanic languages. The language group is also referred to as the Nordic languages, a direct translation of the most common term used among Danish, Faroese, Icelandic,Elfdalian, Norwegian, Gutnish, and Swedish scholars and people. The term ''North Germanic languages'' is used in comparative linguistics, whereas the term Scandinavian languages appears in studies of the modern standard languages and the dialect continuum of Scandinavia. Danish, Norwegian and Swedish are close enough to form a strong mutual intelligibility where cross-border communication in native languages is very common. Approximately 20 million people in the Nordic countries speak a Scandinavian language as their native language,Holmberg, Anders and Christer Platzack (2005). "The Scandinavian la ...

Heavy Metal Umlaut
A metal umlaut is a diacritic that is sometimes used gratuitously or decoratively over letters in the names of mainly hard rock or heavy metal music, heavy metal bands—for example, those of Blue Öyster Cult, Queensrÿche, Motörhead, the Accüsed, Mötley Crüe and the parody bands Spinal Tap (band), Spın̈al Tap, Green Jellÿ and Moxy Früvous. Usage Among English speakers, the use of Umlaut (diacritic), umlaut marks and other diacritics with a blackletter typeface is a form of foreign branding which has been attributed to a desire for a "gothic horror" feel. The metal umlaut is not generally intended to affect the pronunciation of the band's name, unlike the umlaut in German (where the letters ''u'' and ''ü'' represent distinct vowels) and the Scandinavian languages (where å, ä and a, ö/ø and o are distinct letters). History The first gratuitous use of the umlaut in the name of a hard rock or metal band appears to have been by Blue Öyster Cult in 1970. Blue Öyster Cul ...

Underground Zerø
Underground Zerø is a British space rock band, based in Norfolk, UK. The band is also known as UZØ. While the band is often referred to as "Underground Zero" or "Underground Zer0" in print, the official name of the band includes the slashed zero in its name. Their sound is influenced by Hawkwind. The nucleus of UZØ was started in 1979 by Andrew Rix (bass/vocals), Adrian Rix (keyboards), Judi Griggs (vocals), Brian Savage (drums) and Karl Dawson (guitar). From 1981, then known as Ground Zero, the group underwent several major changes. Brian left and was replaced by Mike (Mel) Melnyk and guitarist Paul Holden joined. In 1983 Mel left and was replaced by Sean Holden. The band featured on the UKs Tommy Vance’s Friday Rock Show on Radio 1 and during 1983-85 developed a large following in the new Psychedelic scene. At this point the name became Underground Zerø to avoid confusion with a R & B group in the London Area. They performed at the large open-air concert Anglia for Afr ...

Space Rock
Space rock is a music genre characterized by loose and lengthy song structures centered on instrumental textures that typically produce a hypnotic, otherworldly sound. It may feature distorted and reverberation-laden guitars, minimal drumming, languid vocals, synthesizers and lyrical themes of outer space and science fiction. The genre emerged in late 1960s psychedelia and progressive rock bands such as Pink Floyd, Hawkwind, and Gong who explored a "cosmic" sound. Similar sounds were pursued in the early 1970s West German ''kosmische Musik'' ("cosmic music") scene. Later, the style was taken up in the mid-1980s by Spacemen 3, whose " drone-heavy" sound was avowedly inspired by and intended to accommodate drug use. By the 1990s, space rock developed into shoegazing, stoner rock and post-rock with bands such as the Verve, Flying Saucer Attack, and Orange Goblin.

Teletype Model 33
The Teletype Model 33 is an electromechanical teleprinter designed for light-duty office use. It is less rugged and cost less than earlier Teletype machines. The Teletype Corporation introduced the Model 33 as a commercial product in 1963 after being originally designed for the United States Navy. There are three versions of the Model 33: * Model 33 ASR, (Automatic Send and Receive), which has a built-in eight-hole punched tape reader and tape punch; * Model 33 KSR (Keyboard Send and Receive), which lacks the paper tape reader and punch; * Model 33 RO (Receive Only) which has neither a keyboard nor a reader/punch. The Model 33 was one of the first products to employ the newly-standardized ASCII code, which was first published in 1963. A companion Model 32 used the older, more-established five-bit Baudot code. Because of its low price and ASCII-compatibility, the Model 33 was widely used with early minicomputers, and the large numbers of the teleprinter which were sold strongly ...

ASCII
ASCII ( ), abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Because of technical limitations of computer systems at the time it was invented, ASCII has just 128 code points, of which only 95 are , which severely limited its scope. All modern computer systems instead use Unicode, which has millions of code points, but the first 128 of these are the same as the ASCII set. The Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII for this character encoding. ASCII is one of the IEEE milestones. Overview ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Work on the ASCII standard began in May 1961, with the first meeting of the American Standards Association's (ASA) (now the American National Standards I ...

Teleprinter
A teleprinter (teletypewriter, teletype or TTY) is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations. Initially they were used in telegraphy, which developed in the late 1830s and 1840s as the first use of electrical engineering, though teleprinters were not used for telegraphy until 1887 at the earliest. The machines were adapted to provide a user interface to early mainframe computers and minicomputers, sending typed data to the computer and printing the response. Some models could also be used to create punched tape for data storage (either from typed input or from data received from a remote source) and to read back such tape for local printing or transmission. Teleprinters could use a variety of different communication media. These included a simple pair of wires; dedicated non-switched telephone circuits (leased lines); switched ne ...

Baudot Code
The Baudot code is an early character encoding for telegraphy invented by Émile Baudot in the 1870s. It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the most common teleprinter code in use until the advent of ASCII. Each character in the alphabet is represented by a series of five bits, sent over a communication channel such as a telegraph wire or a radio signal by asynchronous serial communication. The symbol rate measurement is known as baud, and is derived from the same name. History Baudot code (ITA1) In the below table, Columns I, II, III, IV, and V show the code; the Let. and Fig. columns show the letters and numbers for the Continental and UK versions; and the sort keys present the table in the order: alphabetical, Gray and UK Baudot developed his first multiplexed telegraph in 1872 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
