Zero Ring
In ring theory, a branch of mathematics, the zero ring or trivial ring is the unique ring (up to isomorphism) consisting of one element. (Less commonly, the term "zero ring" is used to refer to any rng of square zero, i.e., a rng in which for all ''x'' and ''y''. This article refers to the one-element ring.) In the category of rings, the zero ring is the terminal object, whereas the ring of integers Z is the initial object. Definition The zero ring, denoted or simply 0, consists of the one-element set with the operations + and · defined such that 0 + 0 = 0 and 0 · 0 = 0. Properties * The zero ring is the unique ring in which the additive identity 0 and multiplicative identity 1 coincide. (Proof: If in a ring ''R'', then for all ''r'' in ''R'', we have . The proof of the last equality is found here.) * The zero ring is commutative. * The element 0 in the zero ring is a unit, serving as its own multiplicative inverse. * The unit group of the zero ring is the trivial gr ...

Birthday
A birthday is the anniversary of the birth of a person, or figuratively of an institution. Birthdays of people are celebrated in numerous cultures, often with birthday gifts, birthday cards, a birthday party, or a rite of passage. Many religions celebrate the birth of their founders or religious figures with special holidays (e.g. Christmas, Mawlid, Buddha's Birthday, and Krishna Janmashtami). There is a distinction between birth''day'' and birth''date'': the former, except for February 29, occurs each year (e.g. January 15), while the latter is the complete date when a person was born (e.g. January 15, 2001). Legal conventions In most legal systems, one becomes a legal adult on a particular birthday when they reach the age of majority (usually between 12 and 21), and reaching age-specific milestones confers particular rights and responsibilities. At certain ages, one may become eligible to leave full-time education, become subject to military conscription or to enlist in ...

Ring 0 (computer Security)
In computer science, hierarchical protection domains, often called protection rings, are mechanisms to protect data and functionality from faults (by improving fault tolerance) and malicious behavior (by providing computer security). Computer operating systems provide different levels of access to resources. A protection ring is one of two or more hierarchical ''levels'' or ''layers'' of privilege within the architecture of a computer system. This is generally hardware-enforced by some CPU architectures that provide different CPU modes at the hardware or microcode level. Rings are arranged in a hierarchy from most privileged (most trusted, usually numbered zero) to least privileged (least trusted, usually with the highest ring number). Ring 0 is the level with the most privileges and allows direct interaction with the physical hardware such as certain CPU functionality and chips on the motherboard. Special call gates between rings are provided to allow an outer ring to acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Diacritic
A ring diacritic may appear above or below letters. It may be combined with some letters of the extended Latin alphabets in various contexts. Rings Distinct letter The character Å (å) is derived from an A with a ring. It is a distinct letter in the Danish, Norwegian, Swedish, Finnish, Walloon, and Chamorro alphabets. For example, the 29-letter Swedish alphabet begins with the basic 26 Latin letters and ends with the three letters Å, Ä, and Ö. Overring The character Ů (ů; a Latin U with overring, or kroužek in Czech Republic) is a grapheme in Czech preserved for historic reasons, which identifies a vowel shift. For example, the word for "horse" used to be written ''kóň'', which evolved, along with pronunciation, into ''kuoň''. Ultimately, the vowel disappeared completely, and the ''uo'' evolved into ''ů'', modern form ''kůň''. The letter ''ů'' now has the same pronunciation as the letter '' ú'' (long ), but changes to a short ''o'' when a word is morph ...

Switchboard Operator
In the early days of telephony, companies used manual telephone switchboards, and switchboard operators connected calls by inserting a pair of phone plugs into the appropriate jacks. They were gradually phased out and replaced by automated systems, first those allowing direct dialing within a local area, then for long-distance and international direct dialing. Description A typical telephone switchboard has a vertical panel containing an array of jacks with a desk in front. The desk has a row of switches and two rows of plugs attached to cables that retract into the desk when not in use. Each pair of plugs was part of a cord circuit with a switch associated that let the operator participate in the call or ring the circuit for an incoming call. Each jack had a light above it that lit when the customer's telephone receiver was lifted (the earliest systems required the customer to hand-crank a magneto to alert the central office and, later, to "ring off" the completed call).

Birthday (short Story Collection)
is a story collection by Japanese writer Koji Suzuki and first published on February 5, 1999 in Japan. It is the fourth installment of Suzuki's Ring (Suzuki novel), ''Ring'' series. Plot The book consists of three short stories occurring each in a different timeframe, and are all related to the ''Ring'' universe: Coffin in the Sky (空に浮かぶ棺, ''Sora ni Ukabu Hitsugi'') In November 1990 during the events of ''Spiral (Suzuki novel), Spiral'', Mai Takano finds herself waking up at the bottom of an exhaust shaft of a building near Tokyo Bay. The only way out of the shaft is by climbing a cloth tied to a beam nearby, but her ankle is broken and the shaft is too small for an adult to reasonably move about. To her surprise, Mai also finds out that she is pregnant, despite never having a sexual encounter before. She experiences bouts of leaving and entering unconsciousness and tries to recall her life and the events that made her there. As a former aide of Ryuji Takayama, who ...
