Class (biology)
In biological classification, class () is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name – and not just called a ''top-level genus'' ''(genus summum)'' – was first introduced by French botanist Joseph Pitton de Tournefort in the classification of plants that appeared in his '' Eléments de botanique'' of 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construction, whic ...

Class (Cooper Book)
''Class: A View From Middle England'' is a 1979 book by English author Jilly Cooper that offers a humorous, satirical commentary on the English class system. While categorized as non-fiction, it presents its commentary through fictional characters presented as caricatures of different social classes, illustrating Cooper's views on class distinctions and social behaviours. The book received positive reviews upon publication, although Mary Cadogan described how portrayals of working-class people were less successful than those of other classes. The work has led to Cooper being compared to Nancy Mitford and analysis over subsequent decades after publication has led it to be drawn on as a text, for example in ''Scoff: A History of Food and Class in Britain,'' and it has been analysed by historians and sociologists studying class in Britain, including David Cannadine and Laurie Taylor. Synopsis The book is a humorous, satirical commentary based on the lives of fictional charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class (education)
A class in education has a variety of related meanings. It can be the group of students which attends a specific course or lesson at a university, school, or other educational institution, see '' Form (education)''. It can refer to a course itself, for example, a class in Shakespearean drama. It can be the group of students at the same level in an institution: the freshman class; or the group of students which matriculates to or graduates from the institution at the same time: the Class of 2005. The term can be used in a slightly more general context, such as "the graduating class." Some schools have class reunions, where members of a certain graduating class have the opportunity to meet again, and socialize with each other. It can also refer to the classroom, in the building or venue where such a lesson is conducted. In some countries' educational systems (such as Taiwan's), it can refer to a subdivision of the students in an academic department, consisting of a cohort ...

Type Class
In computer science, a type class is a type system construct that supports ad hoc polymorphism. This is achieved by adding constraints to type variables in parametrically polymorphic types. Such a constraint typically involves a type class T and a type variable a, and means that a can only be instantiated to a type whose members support the overloaded operations associated with T. Type classes were first implemented in the Haskell programming language after first being proposed by Philip Wadler and Stephen Blott as an extension to "eqtypes" in Standard ML, and were originally conceived as a way of implementing overloaded arithmetic and equality operators in a principled fashion. In contrast with the "eqtypes" of Standard ML, overloading the equality operator through the use of type classes in Haskell does not need extensive modification of the compiler frontend or the underlying type system. Overview Type classes are defined by specifying a set of function or constant na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Class File
A Java class file is a file (with the filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM). A Java class file is usually produced by a Java compiler from Java programming language source files ( files) containing Java classes (alternatively, other JVM languages can also be used to create class files). If a source file has more than one class, each class is compiled into a separate class file. Thus, it is called a file because it contains the bytecode for a single class. JVMs are available for many platforms, and a class file compiled on one platform will execute on a JVM of another platform. This makes Java applications platform-independent. History On 11 December 2006, the class file format was modified under Java Specification Request (JSR) 202. File layout and structure Sections There are 10 basic sections to the Java class file structure: * Magic Number: 0xCAFEBABE * Version of Class File Format: the minor and maj ...

Complexity Class
In computational complexity theory, a complexity class is a set (mathematics), set of computational problems "of related resource-based computational complexity, complexity". The two most commonly analyzed resources are time complexity, time and space complexity, memory. In general, a complexity class is defined in terms of a type of computational problem, a model of computation, and a bounded resource like time complexity, time or space complexity, memory. In particular, most complexity classes consist of decision problems that are solvable with a Turing machine, and are differentiated by their time or space (memory) requirements. For instance, the class P (complexity), P is the set of decision problems solvable by a deterministic Turing machine in polynomial time. There are, however, many complexity classes defined in terms of other types of problems (e.g. Counting problem (complexity), counting problems and function problems) and using other models of computation (e.g. probabil ...

Class Attribute (HTML)
HTML attributes are special words used to adjust the behavior or display of an ''HTML element''. An attribute either modifies the default functionality of an element type or provides functionality to certain element types unable to function correctly without them. In HTML syntax, an attribute is added to an '' HTML start tag''. Several basic attributes types have been recognized, including: (1) ''required attributes'' needed by a particular element type for that element type to function correctly; (2) ''optional attributes'' used to modify the default functionality of an element type; (3) ''standard attributes'' supported by many element types; and (4) ''event attributes'' used to cause element types to specify scripts to be run under specific circumstances. Doctype HTML is a declaration that tells the browser what version of HTML the document is written in. Some attribute types function differently when used to modify different element types. For example, the attribute ''name'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C++ Classes
A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers ''private'', ''protected'' or ''public''. By default access to members of a C++ class declared with the keyword class is ''private''. The private members are not accessible outside the class; they can be accessed only through member functions of the class. The public members form an interface to the class and are accessible outside the class. Instances of a class data type are known as objects and can contain member variables, constants, member functions, and overloaded operators defined by the programmer. Differences between a struct and a class in C++ In C++, a class defined with the class keyword has private members and base classes by default. ...

Class (warez)
CLASS (CLS) was a notorious and prolific warez group that existed between January 1, 1997, and January 9, 2004. The group was the target of federal raids such as Operation Fastlink. They specialized in cracked games, and sometimes had elaborate art in the cracktro or release (i.e. music, 3D animation, logo designs, etc.). They were a global group and had many members worldwide. Class used their group abbreviation, ''CLS'', as a suffix at the end of the files they released. According to an interview of the famous Australian cracker Grudge, a few people from the Prestige warez group split and became Class. Class was involved in a long-standing rivalry with a competing game pirating group known as MYTH. The two groups released strictly ripped games, as opposed to the CD image content released by groups such as Fairlight. Games would be split into the base rip, which would have as little content as possible to fully play the game; additional media (usually movies or digital musi ...

Class (computer Programming)
In object-oriented programming, a class defines the shared aspects of objects created from the class. The capabilities of a class differ between programming languages, but generally the shared aspects consist of state ( variables) and behavior ( methods) that are each either associated with a particular object or with all objects of that class. Object state can differ between each instance of the class whereas the class state is shared by all of them. The object methods include access to the object state (via an implicit or explicit parameter that references the object) whereas class methods do not. If the language supports inheritance, a class can be defined based on another class with all of its state and behavior plus additional state and behavior that further specializes the class. The specialized class is a ''sub-class'', and the class it is based on is its ''superclass''. Attributes Object lifecycle As an instance of a class, an object is constructed from a class via '' ...
