What is "generator"

Generator \Gen"er*a`tor\, n. [L.]

1. One who, or that which, generates, begets, causes, or produces.

2. An apparatus in which vapor or gas is formed from a liquid or solid by means of heat or chemical process, as a steam boiler, gas retort, or vessel for generating carbonic acid gas, etc.

3. (Mus.) The principal sound or sounds by which others are produced; the fundamental note or root of the common chord; -- called also generating tone.

4. (Elec.) Any machine that transforms mechanical into electrical energy; a dynamo.

5. (Math.) a mathematical entity which, when subjected to an operation, yields another mathematical entity; also, a generatrix.

1640s, "person or thing that generates," from Latin generator "a begetter, producer," agent noun from past participle stem of generare (see generation). Meaning "machine that generates power" first recorded 1794; in sense of "machine that generates electric energy," 1879. Fem. generatrix attested from 1650s.

"Generator" is a Foo Fighters song, released as a single in 2000 from their third album There Is Nothing Left to Lose. The single was only released in Australia and also released as a limited edition single in Europe.

The song is particularly unique among the band's work because of Dave Grohl's implementation of the talk box in parts of the song. The usage of the device was partly inspired by Grohl's admiration of Peter Frampton and Joe Walsh, both of whom helped popularize it in the 1970s.

Generator is the fourth studio album by the Italian/ Norwegian industrial black metal band Aborym. Former vocalist Attila Csihar makes a guest appearance on this album, performing vocals on "Man Bites God". Vocals on the rest of the album are performed by Prime Evil.

This is Aborym's first album to feature a human drummer as opposed to a drum machine. It is also the last to feature longtime guitarist Nysrok Infernalien.

Generator may refer to:

• Signal generator, electronic devices that generate repeating or non-repeating electronic signals
• Electric generator, a device that converts mechanical energy to electrical energy
• Generator (circuit theory), an element in an abstract circuit providing a source of electricity
• Engine-generator, an electric generator with its own engine
• Wearable generator, a hypothetical generator that can be worn on the human body
• Gas generator a device, often similar to a solid rocket or a liquid rocket that burns to produce large volumes of relatively cool gas.
• Motor–generator, a device for converting electrical power to another form

Generator is the sixth studio album by the punk rock band Bad Religion. Although the album was completed in the spring of 1991, it was not released until 1992. The reason that the album's release date was pushed back was because Bad Religion was not happy with the artwork and packaging, and in order to release it, they went through ideas that were scrapped. Generator was the band's first release with drummer Bobby Schayer, who replaced Pete Finestone during the Against the Grain tour. It is also Bad Religion's fourth album (and last, until 2002's The Process of Belief) not to display their classic font on the cover.

Like Bad Religion's first five albums (minus Into the Unknown), Epitaph Records released a remastered version of Generator on April 6, 2004, with two exclusive tracks that were taken from the split 7" with Noam Chomsky issued by Maximum Rock'N Roll in 1991. On the same day, they released a DVD reissue of their long-out of print live video Along the Way, which was also released in 1992. These versions feature Finestone on drums, making it his final recordings with Bad Religion. As of 2008, the original CD version of the album is out of print.

A video was made for "Atomic Garden". It is available for watching at Epitaph web site. This was the first video Bad Religion ever released.

The album includes some fan favorites and concert staples, such as, "Generator", "No Direction", "Heaven Is Falling", "Atomic Garden", and "The Answer".

In computer science, a generator is a special routine that can be used to control the iteration behaviour of a loop. In fact, all generators are iterators. A generator is very similar to a function that returns an array, in that a generator has parameters, can be called, and generates a sequence of values. However, instead of building an array containing all the values and returning them all at once, a generator yields the values one at a time, which requires less memory and allows the caller to get started processing the first few values immediately. In short, a generator looks like a function but behaves like an iterator.

Generators can be implemented in terms of more expressive control flow constructs, such as coroutines or first-class continuations. Generators, also known as semicoroutines, are a special case of (and weaker than) coroutines, in that they always yield control back to the caller (when passing a value back), rather than specifying a coroutine to jump to; see comparison of coroutines with generators.

In mathematics and physics, the term generator or generating set may refer to any of a number of related concepts. The underlying concept in each case is that of a smaller set of objects, together with a set of operations that can be applied to it, that result in the creation of a larger collection of objects, called the generated set. The larger set is then said to be generated by the smaller set. It is commonly the case that the generating set has a simpler set of properties than the generated set, thus making it easier to discuss and examine. It is usually the case that properties of the generating set are in some way preserved by the act of generation; likewise, the properties of the generated set are often reflected in the generating set.

"Generator" is the first, fourth and sixth single from the North London indie group The Holloways. The initial limited release wasn't chart eligible as it was only available from one shop on Holloway Road. The first re-release debuted at #30 in the UK Singles Chart. It was included in The Holloways' debut album So This is Great Britain?.

The song was performed by The Holloways on BBC Radio 1's Live Lounge. It was released on Radio 1's Live Lounge – Volume 2.

It was re-released again on 11 June 2007 and entered the UK Top 20 at #14, marking the band's highest charting single to date. It had spent 12 non-consecutive weeks in the UK Top 100.

In category theory in mathematics a family of generators (or family of separators) of a category $\mathcal C$ is a collection $\{G_i\in Ob(\mathcal C)|i\in I\}$ of objects, indexed by some set I, such that for any two morphisms f, g : X → Y in $\mathcal C$, if f ≠ g then there is some i∈I and morphism h : G → X, such that the compositions f ∘ h ≠ g ∘ h. If the family consists of a single object G, we say it is a generator (or separator).

Generators are central to the definition of Grothendieck categories.

The dual concept is called a cogenerator or coseparator.

A generator in electrical circuit theory is one of two ideal elements: an ideal voltage source, or an ideal current source. These are two of the fundamental elements in circuit theory. Real electrical generators are most commonly modelled as a non-ideal source consisting of a combination of an ideal source and a resistor. Voltage generators are modelled as an ideal voltage source in series with a resistor. Current generators are modelled as an ideal current source in parallel with a resistor. The resistor is referred to as the internal resistance of the source. Real world equipment may not perfectly follow these models, especially at extremes of loading (both high and low) but for most purposes they suffice.

The two models of non-ideal generators are interchangeable, either can be used for any given generator. Thévenin's theorem allows a non-ideal current source model to be converted to a non-ideal voltage source model and Norton's theorem allows a non-ideal voltage source model to be converted to a non-ideal current source model. Both models are equally valid, but the voltage source model is more applicable to when the internal resistance is low (that is, much lower than the load impedance) and the current source model is more applicable when the internal resistance is high (compared to the load).
