Information: - PlayStation Network (PSN) is a digital media entertainment service provided by Sony Interactive Entertainment. Launched in November 2006, PSN was originally conceived for the PlayStation video game consoles, but soon extended to encompass smartphones, tablets, Blu-ray players and high-definition televisions. As of April 2016, over 110 million users have been documented, with 65 million of them active monthly. - The PlayStation Portable (PSP) is a handheld game console developed by Sony. Development of the console was announced during E3 2003, and it was unveiled on , 2004, at a Sony press conference before E32004. The system was released in Japan on , 2004, in North America on , 2005, and in the PAL region on , 2005. It primarily competed with the Nintendo DS, as part of the seventh generation of video games. - The PlayStation 3 (abbreviated as PS3) is a home video game console developed by Sony Computer Entertainment. It is the successor to PlayStation 2, and is part of the PlayStation brand of consoles. It competed with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles. It was first released on November 11, 2006, in Japan, November 17, 2006 in North America, and March 27, 2007 in Europe and Australia. - Feel Ski ( Go ! Sports Ski in North America and Japan ) is a downloadable game released on the PlayStation Store on October 4 , 2007 . - Downloadable content (DLC) is additional content created for a released video game. It is distributed through the Internet by the game's official publisher. Downloadable content can be of several types, ranging from aesthetic outfit changes to a new, extensive storyline, similar to an expansion pack. As such, DLC may add new game modes, objects, levels, challenges or other features to a complete, already released game. - Digital media is any media that is encoded in a machine-readable format. Digital media can be created, viewed, distributed, modified and preserved on digital electronics devices. Computer programs and software; digital imagery, digital video; video games; web pages and websites, including social media; data and databases; digital audio, such as mp3s; and e-books are examples of digital media. Digital media are frequently contrasted with print media, such as printed books, newspapers and magazines, and other traditional or analog media, such as pictures, film or audio tape. - The PlayStation Store (also abbreviated as PSN Store) is a digital media store available to users of Sony's PlayStation 3, PlayStation 4, PlayStation Vita and PlayStation Portable game consoles via the PlayStation Network. The store offers a range of downloadable content both for purchase and available free of charge. Available content includes full games, add-on content, playable demos, themes and game/movie trailers.

Information: - A cyclic compound ("ring compound") is a term for a compound in the field of chemistry in which one or more series of atoms in the compound is connected to form a ring. Rings may vary in size from three to many atoms, and include examples where all the atoms are carbon (i.e., are carbocycles), none of the atoms are carbon (inorganic cyclic compounds), or where both carbon and non-carbon atoms are present (heterocyclic compounds). Depending on the ring size, the bond order of the individual links between ring atoms, and their arrangements within the rings, carbocyclic and heterocyclic compounds may be aromatic or non-aromatic, in the latter case, they may vary from being fully saturated to having varying numbers of multiple bonds between the ring atoms. Because of the tremendous diversity allowed, in combination, by the valences of common atoms and their ability to form rings, the number of possible cyclic structures, even of small size (e.g., <17 total atoms) numbers in the many billions. - Dihydrothiophene is a heterocyclic compound . - Substitution reaction (also known as single displacement reaction or single replacement reaction) is a chemical reaction during which one functional group in a chemical compound is replaced by another functional group. Substitution reactions are of prime importance in organic chemistry. Substitution reactions in organic chemistry are classified either as electrophilic or nucleophilic depending upon the reagent involved. There are other classifications as well that are mentioned below. - Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behavior of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivities of individual organic molecules, both in the laboratory and via theoretical (in silico) study. - Thiophene, also commonly called thiofuran, is a heterocyclic compound with the formula CHS. Consisting of a flat five-membered ring, it is aromatic as indicated by its extensive substitution reactions. Related to thiophene are benzothiophene and dibenzothiophene, containing the thiophene ring fused with one and two benzene rings, respectively. Compounds analogous to thiophene include furan (CHO) and pyrrole (CHNH). - A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). Heterocyclic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of these heterocycles.
