Fourth-generation Programming Language
A fourth-generation programming language (4GL) is a high-level programming language, high-level 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 layer, 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 generator, report generation, mathematical optimization, graphical user interface (GUI) Graphical user interface builder, development, or web development. Some researchers state that 4GLs are a subset of domain-specific languages. The concept of 4GL was developed from th ...

Fourth-generation Jet Fighter
The fourth-generation fighter is a Jet fighter generations, 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. Jet fighter generations#Third generation, Third-generation fighters were often designed primarily as Interceptor aircraft, interceptors, being built around speed and Air-to-air missile, air-to-air missiles. While exceptionally fast in a straight line, many third-generation fighters severely lacked in maneuverability, as doctrine held that traditional Dogfight, 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 i ...

Fourth Generation Warfare
Fourth-generation warfare (4GW) is conflict characterized by a blurring of the distinction between war and politics, and of the distinction between combatants and civilians. It is placed as succeeding the third generation in the five-generation model of military theory. 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 a ...

Generation IV Reactor
Generation IV (Gen IV) reactors are nuclear reactor design technologies that are envisioned as successors of generation III reactors. The Generation IV International Forum (GIF) – an international organization that coordinates the development of generation IV reactors – specifically selected six reactor technologies as candidates for generation IV reactors. The designs target improved safety, sustainability, efficiency, and cost. The World Nuclear Association in 2015 suggested that some might enter commercial operation before 2030. No precise definition of a Generation IV reactor exists. The term refers to nuclear reactor technologies under development as of approximately 2000, and whose designs were intended to represent 'the future shape of nuclear energy', at least at that time. The six designs selected were: the gas-cooled fast reactor (GFR), the lead-cooled fast reactor (LFR), the molten salt reactor (MSR), the sodium-cooled fast reactor (SFR), the supercritical-water-cool ...

History Of Video Game Consoles (fourth Generation)
In the history of video games, the fourth generation of video 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 (known as the Sega Genesis in North America) and the Super Nintendo Entertainment System (known as the ''Super Famicom'' in Japan). Cartridge-based handheld game consoles became prominent during this time, such as the Nintendo Game Boy, Atari Lynx, Sega Game Gear and TurboExpress. Nintendo was able to capitalize on its success in the third generation, and managed to win the largest worldwide market share in the fourth generation as well. However, particularly in the lucrative North American market, there was a fierce console war that raged through the early 1990s, w ...

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. The Pan American Nikkei Association (PANA) includes Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, P ...

List Of Generation IV Pokémon
The fourth generation (generation IV) of the ''Pokémon'' franchise features 107 fictional species of creatures introduced to the core video game series in the 2006 Nintendo DS games ''Pokémon Diamond'' and ''Pearl''. Some Pokémon in this generation were introduced in games and animated adaptations of the franchise before ''Diamond'' and ''Pearl'', such as Bonsly, Mime Jr., and Munchlax, which were recurring characters in the ''Pokémon'' anime series in 2005 and 2006. The following list details the 107 Pokémon of generation IV in order of their National Pokédex number. The first Pokémon, Turtwig, is number 387 and the last, Arceus, is number 493. Alternate forms that result in type changes are included for convenience. Mega Evolutions and regional forms are included on the pages for the generation in which they were introduced. Design and development Pokémon are a species of fictional creatures created for the ''Pokémon'' media franchise. Developed by Game Frea ...
