Fourth-generation Programming Language
A fourth-generation programming language (4GL) is any computer programming language that belongs to a class of languages envisioned as an advancement upon third-generation programming languages (3GL). Each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details, making the language more programmer-friendly, powerful, and versatile. While the definition of 4GL has changed over time, it can be typified by operating more with large collections of information at once rather than focusing on just bits and bytes. Languages claimed to be 4GL may include support for database management, report generation, mathematical optimization, GUI development, or web development. Some researchers state that 4GLs are a subset of domain-specific languages. The concept of 4GL was developed from the 1970s through the 1990s, overlapping most of the development of 3GL, with 4GLs identified as "non-procedural" or "program-generating" l ...

Fourth-generation Jet Fighter
The fourth-generation fighter is a class of jet fighters in service from around 1980 to the present, and represents design concepts of the 1970s. Fourth-generation designs are heavily influenced by lessons learned from the previous generation of combat aircraft. Third-generation fighters were often designed primarily as interceptors, being built around speed and air-to-air missiles. While exceptionally fast in a straight line, many third-generation fighters severely lacked in manoeuvrability, as doctrine held that traditional dogfighting would be impossible at supersonic speeds. In practice, air-to-air missiles of the time, despite being responsible for the vast majority of air-to-air victories, were relatively unreliable, and combat would quickly become subsonic and close-range. This would leave third-generation fighters vulnerable and ill-equipped, renewing an interest in manoeuvrability for the fourth generation of fighters. Meanwhile, the growing costs of military aircraft in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fourth Generation Warfare
Fourth-generation warfare (4GW) is conflict characterized by a blurring of the lines between war and politics, combatants and civilians. The term was first used in 1980 by a team of United States analysts, including William S. Lind, to describe warfare's return to a decentralized form. In terms of generational modern warfare, the fourth generation signifies the nation states' loss of their near-monopoly on combat forces, returning to modes of conflict common in pre-modern times. The simplest definition includes any war in which one of the major participants is not a state but rather a violent non-state actor. Classical examples of this type of conflict, such as the slave uprising under Spartacus, predate the modern concept of warfare. Elements Fourth-generation warfare is defined as conflicts which involve the following elements: * Complex and long term * Terrorism (tactic) * A non-national or transnational base – highly decentralized * A direct attack on the enemy's culture, ...

Generation IV Reactor
Generation IV reactors (Gen IV) are six nuclear reactor designs recognized by the Generation IV International Forum. The designs target improved safety, sustainability, efficiency, and cost. The most developed Gen IV reactor design is the sodium fast reactor. It has received the greatest share of funding that supports demonstration facilities, as well as two commercial reactors in Russia. One of these has been in commercial operation since 1981. Its principal Gen IV features relates its sustainable closed fuel cycle. Moir and Teller consider the molten-salt reactor, a less developed technology, as potentially having the greatest inherent safety of the six models. The very-high-temperature reactor designs operate at much higher temperatures than prior generations. This allows for high temperature electrolysis or for sulfur–iodine cycle for the efficient production of hydrogen and the synthesis of carbon-neutral fuels. The first commercial plants are not expected before 2040–2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Video Game Consoles (fourth Generation)
In the history of video games, the fourth generation of game consoles, more commonly referred to as the 16-bit era, began on October 30, 1987, with the Japanese release of NEC Home Electronics' PC Engine (known as the TurboGrafx-16 in North America). Though NEC released the first console of this era, sales were mostly dominated by the rivalry between Sega and Nintendo across most markets: the Sega Mega Drive (''Sega Genesis'' in North America) and the Super Nintendo Entertainment System (SNES; ''Super Famicom'' in Japan). Cartridge-based handheld consoles became prominent during this time, such as the Nintendo Game Boy (1989), Atari Lynx (1989), Sega Game Gear (1990) and TurboExpress (1990). Nintendo was able to capitalize on its success in the previous, third generation, and managed to win the largest worldwide market share in the fourth generation as well. Sega, however, was extremely successful in this generation and began a new franchise, Sonic the Hedgehog, to compete with ...

Yonsei (Japanese Diaspora)
is a Japanese diasporic term used in countries, particularly in North America and in Latin America, to specify the great-grandchildren of Japanese immigrants (Issei). The children of Issei are Nisei (the second generation). Sansei are the third generation, and their offspring are Yonsei. For the majority of Yonsei in the Western hemisphere, their Issei ancestors emigrated from Japan between the 1880s and 1924. The character and uniqueness of the ''Yonsei'' is recognized in its social history. The ''Yonsei'' are the subject of ongoing academic research in the United States and Japan. History The earliest organized group of Japanese emigrants settled in Mexico in 1897.Ministry of Foreign Affairs ''Japan-Mexico Foreign Relations''/ref> Today, the four largest populations of Japanese and descendants of Japanese immigrants live in Brazil, the United States, Canada and Peru. ''Yonsei'' is a term used in geographic areas outside Japan to specify the child of at least one ''Sansei'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
