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.
Applications. v. t. e. In programming language theory, semantics is the rigorous mathematical study of the meaning of programming languages. [ 1] Semantics assigns computational meaning to valid strings in a programming language syntax. It is closely related to, and often crosses over with, the semantics of mathematical proofs .
Computer science. Computer science is the study of computation, information, and automation. [ 1][ 2][ 3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software ). [ 4][ 5][ 6] Algorithms and data ...
In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers machine code is "the binary representation of a computer program which is actually read and interpreted by the computer. A program in machine ...
The prototype pattern is a creational design pattern in software development. It is used when the types of objects to create is determined by a prototypical instance, which is cloned to produce new objects. This pattern is used to avoid subclasses of an object creator in the client application, like the factory method pattern does, and to avoid ...
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages, where the document represents source code, and to markup languages, where the document represents data.
Abstraction (computer science) In software engineering and computer science, abstraction is the process of generalizing concrete details, [ 1] such as attributes, away from the study of objects and systems to focus attention on details of greater importance. [ 2] Abstraction is a fundamental concept in computer science and software engineering ...
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects. It provides a means to associate metadata with a class where the language does not have explicit support for such metadata. To use this pattern, a class implements a marker interface[ 1] (also called ...
