  2. Primitive data type - Wikipedia

    en.wikipedia.org/wiki/Primitive_data_type

    In computer science, primitive data types are a set of basic data types from which all other data types are constructed. [1] Specifically it often refers to the limited set of data representations in use by a particular processor , which all compiled programs must use.

  3. Data type - Wikipedia

    en.wikipedia.org/wiki/Data_type

    Data types may be categorized according to several factors: Primitive data types or built-in data types are types that are built-in to a language implementation. User-defined data types are non-primitive types. For example, Java's numeric types are primitive, while classes are user-defined.

  4. Value type and reference type - Wikipedia

    en.wikipedia.org/wiki/Value_type_and_reference_type

    Primitive data types, such as Booleans, fixed-size integers, floating-point values, and characters, are value types. Objects, in the sense of object-oriented programming, belong to reference types. Assigning to a variable of reference type simply copies the reference, whereas assigning to a variable of value type copies the value.

    1.2 Composite types or non-primitive type. 1.3 Abstract data types. ... Many graph-based data structures are used in computer science and related fields: Graph;

  6. Data structure - Wikipedia

    en.wikipedia.org/wiki/Data_structure

    A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.

  7. X.690 - Wikipedia

    en.wikipedia.org/wiki/X.690

    X.680 defines a syntax for declaring data types, for example: booleans, numbers, strings, and compound structures. Each type definition also includes an identifying number. X.680 defines several primitive data types, for example: BooleanType, IntegerType, OctetStringType.

  8. Talk:Data type - Wikipedia

    en.wikipedia.org/wiki/Talk:Data_type

    [3] also lists enumerations as composite, although there the terminology is scalar vs composite rather than primitive vs composite. R.e. your definition of composite, IMO a type with accessible components is an aggregate type. This currently redirects to composite type, due to being used interchangeably in the database field, but I would argue ...

  9. Boxing (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Boxing_(computer_programming)

    In computer science, boxing (a.k.a. wrapping) is the transformation of placing a primitive type within an object so that the value can be used as a reference. Unboxing is the reverse transformation of extracting the primitive value from its wrapper object. Autoboxing is the term for automatically applying boxing and/or unboxing transformations ...
