Keyboard technology - Keyboard technology There are several types of keyboard, usually differentiated by the switch technology employed in their operation. Since there are so many switches needed (usually about 80-110) and because they have to be highly reliable, this usually defines the keyboard. The choice of switch technology affects key response (the positive feedback that a key has been pressed) and travel (the distance needed to push the key to reliably enter a character). Newer models use hybrids of various technologies to achieve greater cost savings. Dome switch keyboard Dome switch keyboards are kind of a hybrid of membrane and mechanical keyboards. They bring two circuit board traces together under a plastic "dome" or bubble. The top of the bubble is coated in some conductive substance. When a.
Chorded keyboard - Chorded keyboard A chorded keyboard (sometimes called chording keyboard or simply chord keyboard) is a computer input device. Instead of using one key for each character, as on a QWERTY keyboard, the user presses multiple-key combinations, similar to the playing of chordss on a guitar. Such technology has been around for many years, possibly originating from Doug Engelbart, inventor of the computer mouse, but is little known to the public because special training is needed to use it. For example, each finger might control one key which corresponds to one bit in a byte, so that one to eight fingers can enter any character in the ASCII set if the user can remember the binary codes. There are many different designs based on the same concept, some.
Computer keyboard - Computer keyboard QWERTY computer keyboard Larger version A computer peripheral modelled after the typewriter keyboard. Designed to be used by a human to enter data by manual depression of keys. Most keyboards have characters engraved or printed on the keys, these usually represent characters selected from some language alphabet along with numbers and punctuation and other control keys. Different keyboards may have different keys or keys laid out in different ways, this is the subject of keyboard layout. In English speaking countries, the QWERTY layout is nearly universal. In countries speaking other Latin alphabet languages, small variations on QWERTY can be found; the Brazilian Portuguese and Spanish keyboard layouts, for example, while having enough differences to disrupt a QWERTY typist's fluency, have many more keys in common.
Virtual reality - can create an almost complete impression of the simulated environment.) Users can often interactively manipulate a VR environment, either through standard input devices like a keyboard, or through specially designed devices like a cyberglove. The simulated environment can be similar to the real world--for example, in simulations for pilot or combat training--or it can differ significantly from reality, as in the simulation of molecules, or in VR games. In practice, it is very difficult to create a convincing virtual reality experience, due largely to limitations on processing power. Virtual reality originally denoted a fully immersive system, although it has since been used to describe systems lacking cybergloves etc., such as VRML on the World Wide Web and occasionally even text-based interactive systems such as MOOs or MUDs. The term virtual reality.
Jumper (computing) - live circuit). When a jumper shunt goes over two (or more) jumper pins, current is carried across, and the electronic equipment is thus instructed to activate certain settings acordingly. For example, computer CPU speed and voltage settings are often made by setting jumpers. Informally, technicians often call setting jumpers "strapping". To adjust the SCSI ID jumpers on a hard drive, for example is to "strap it up". As a general rule, the early generations of any given technology have many jumpers, often laid out in a way that is badly documented and difficult to set correctly. As time goes by, the designers find ways to streamline and simplify the jumper layout. For example, a typical early model Intel 386 motherboard might have 30 or 40 jumper pairs, while the final production.

Internet art - 1994-1999; these are usually referenced as Vuk Cosic, Jodi.org, Alexei Shulgin, Olia Lialina and Heath Bunting. This can be misleading, however, as other artists were working at the same time: Superbad (Ben Benjamin), Snarg, Zuper (Michael Samyn), and I/O/D (Collective) to name but a few.

Some Internet art projects are particularly related to conceptual art, Fluxus, pop art and performance art. Internet art is also historically related to the interdisciplinary field of technology-centered or electronic art which has developed since the 1970s in research institutes and specialized art centers throughout Europe, Japan and the United States - outside the regular, "non-technological" museum.
Innovations in the piano - piano buyers might actually be suspicious of pianos that are made differently from the older kind. Yet piano manufacturers, especially the smaller ones, are still experimenting with ways to build better pianos. In the early 21st century, the obvious way to raise the technological level of any mechanical device is to use digital technology to control it (compare the mid 19th century, where the obvious route was to make some of its parts from steel; e.g. piano strings). Of course, digital technology has been incorporated into pianos, and this innovation is discussed below. But in a sense, it is a far greater challenge is to improve the piano in its own terms, as a mechanical/acoustic device. This challenge pits the modern piano designer against some of the finest engineering minds of.
Hall effect - proportional to the applied magnetic field, and digital Hall effect sensors, which are often used as magnetically controlled switches -- they turn on or off when the applied magnetic field reaches a certain level. These Hall effect switches generally consist of a Hall effect sensor]], one or more logic gates and a transistor used to switch the electric current on or off. Alternately, by applying a known magnetic field (typically from a permanent magnet) one can use the Hall voltage to instead measure the current through the element. This can be particularly useful as it allows one to measure the current in a conductor remotely through induction. This is widely used commercially in "live wire detectors", which allow you to quickly identify which wires are carrying current without plugging into them..
Heavy metal music - that arose when musicians started to exploit the opportunities of the electrically amplified guitar to produce a louder, more discordant sound. Where blues-rock drumming styles had been largely simple shuffle beats on small drum kits, drummers began using a more muscular, complex, and amplified approach to match and be heard with the increasingly loud guitar sounds; similarly vocalists modified their technique and increased their reliance on amplification, often becoming more stylized and dramatic in the process. Simultaneous advances in amplification and recording technology made it possible to successfully capture the power of this heavier approach on record. The earliest music commonly identified as heavy metal came out of Great Britain in the late 1960s as bands such as Led Zeppelin and Black Sabbath applied an overtly non-traditional approach to blues standards.
Hirokazu 'Hip' Tanaka - of music. Tanaka became interested in rock music when the TV show The Monkees aired in Japan when he was nine, which prompted him to start a band with some friends. From nine to 30, Tanaka played in and out of groups on various instruments, including guitar, keyboard, and drums, and in various styles from rock to jazz and fusion. Tanaka entered college as an electronic engineering major, but he saw little success since he was more interested in electronic applications for music than what his professors considered more useful pursuits. In 1980, Tanaka saw a newspaper advertisement for a sound engineer position at the Nintendo video game company, a position he secured for himself. Meanwhile, his current band had made the finals in a music competition, a major breakthrough in.
Home computer - few types remained for much longer, some, such as the BBC Micro and Commodore 64 still having a devoted following. However by the end of the decade most were squeezed out between the IBM compatible Personal Computer and the newer generations of video game consoles because they each used their own incompatible formats. The IBM revolution was caused by the 1981 release of the IBM PC (5150). Many of these computers were superficially similar, having a usually very cheap-to-manufacture keyboard integrated into the processor unit and displaying output on a home television. Many used compact audio cassettes as a (notoriously unreliable) storage mechanism since floppy disk drives were very expensive at the time. Cheapness was the order of the day for most of these machines. Almost all computers employ an operating.
Gothic rock - verses & choruses. Early Gary Numan material from Tubeway Army to The Pleasure Principle can be considered to be goth, although the image was new wave. The use of analog synths and subject matter were a definite influence on later goth bands. His imagery & fashion have influenced contemporary goth Cyberpunk fashion. The band which has most influenced contemporary Goth music is The Sisters of Mercy, which is significantly different from the original sound of Gothic music. Stemming from these changes, a movement of Goth dance music was created. Contemporary Goth music is generally sequenced, making heavy use of FM & digital synths. It is characterized by a crisp snare drum sample and a heavy bass drum sample. The auto-arpeggiate feature of modern synthesizers is used in often complex sounding multiple.
A.R. Rahman - RamGopal Varma's movie Rangeela (means: colorful) (1995) in Hindi. At the age of 11, Rahman joined the troupe of Indian composer Ilayaraja as a keyboard player. He later played on the orchestra of M.S. Vishwanathan and Ramesh Nadu, and accompanied Zakir Hussain and Kunnakudi Vaidyanathan on world tours, the experience of which allowed him to obtain a scholarship to the Trinity College of Music at Oxford University, from where he received a degree in WesternClassical Music. In 1989, Rahman began his own studio (which was attached to his house), called the Panchathan Record Inn. He initially composed music for use in advertisements, the title music on popular Indian television channels, and in documentaries, among other projects. Rahman was, at first, hesitant about composing music for the Indian film industry primarily because.

Amiga - and nasty 'game machines' - this image was not helped by the fact that most retail outlets were toy stores, and by Commodore's marketing campaigns which were woefully mismatched with the status-conscious American public. As a home computer, compatibility with ordinary household television sets was prioritized over professional grade graphics and memory management. Even "amenities" such as a hard drive (on a 500) or a device for ensuring a non-interlaced display (a 'flicker fixer') had to be bought from third party vendors. While it was the only multitasking platform in the consumer marketplace for several years, robustness left something to be desired (mainly due to the absence of Protected memory, resulting in frequent "Guru Meditation" errors). In spite of being sold short, Amiga was originally supported by such prestigious software titles.
Television - television channels, such as HBO and Sky. Practically every country with the technological capability has developed at least one television channel. TV Standards The standard adopted by the US was called NTSC, which stood for National Television Standards Committee. NTSC is the television standard in the US, Canada, and Japan. Germany developed the television standard called PAL, which stood for Phase Alternating Line, and introduced it in 1967. PAL is the television standard in the United Kingdom, much of Europe, Africa, Australia, and some parts of South America. The French developed in 1967 the television standard called SECAM, Sequentiel Couleur avec Mémoire, French for "sequential color with memory". The SECAM standard was used mostly in France and Eastern European "Warsaw Pact" countries. There are various kinds of television broadcast systems: Terrestrial.
Calculator - as many of today's computers. The first mechanical calculators were mechanical desktop devices, which were soon replaced by electromechanical desktop calculators, and then by electronic devices using first thermionic valves, then transistors, then hard-wired integrated circuit logic. A pocket calculator is a small battery-powered or solar powered electronic digital computer made possible by integrated circuit and semiconductor technology. Typically they are limited to an 8 – 10 digit single-number display and a few basic functions of arithmetic, but some modern ones have more of the features of a general-purpose computer. Pocket calculators rendered the slide rule obsolete. Calculators vary in their capabilities. Some are limited to only basic arithmetic; others support trigonometric and other mathematical functions. The most advanced modern calculators are programmable, can display graphics, and include features of computer.
