He was highly influential in the development of computer science, giving a formalisation of the concepts of " algorithm " and " computation " with the Turing machine, which can be considered a model of a general purpose computer.

Turing is widely considered to be the father of computer science and artificial intelligence.

In algorithmic information theory ( a subfield of computer science ), the Kolmogorov complexity of an object, such as a piece of text, is a measure of the computational resources needed to specify the object.

Algorithmic information theory is the area of computer science that studies Kolmogorov complexity and other complexity measures on strings ( or other data structures ).

In computer science, an array data structure or simply an array is a data structure consisting of a collection of elements ( values or variables ), each identified by at least one array index or key.

The term is also used, especially in the description of algorithms, to mean associative array or " abstract array ", a theoretical computer science model ( an abstract data type or ADT ) intended to capture the essential properties of arrays.

In computer science, an AVL tree is a self-balancing binary search tree, and it was the first such data structure to be invented.

In computer science, the analysis of algorithms is the determination of the number of resources ( such as time and storage ) necessary to execute them.

Run-time efficiency is a topic of great interest in computer science: A program can take seconds, hours or even years to finish executing, depending on which algorithm it implements ( see also performance analysis, which is the analysis of an algorithm's run-time in practice ).

In computer science, an abstract data type ( ADT ) is a mathematical model for a certain class of data structures that have similar behavior ; or for certain data types of one or more programming languages that have similar semantics.

This cutting-edge technology has a promising potential of leading a new revolution in science as integrated circuits did in computer developments.

In a category with exponentials, using the isomorphism ( in computer science, this is called currying ), the Ackermann function may be defined via primitive recursion over higher-order functionals as follows:

DBMSs can be categorized according to the database model ( s ) that they support, such as relational or XML, the type ( s ) of computer they support, such as a server cluster or a mobile phone, the query language ( s ) that access the database, such as SQL or XQuery, performance trade-offs, such as maximum scale or maximum speed or others.

In computer science, domain relational calculus ( DRC ) is a calculus that was introduced by Michel Lacroix and Alain Pirotte as a declarative database query language for the relational data model.

In computer science, multiple granularity locking ( MGL ), sometimes called the John Rayner locking method, is a locking method used in database management systems ( DBMS ) and relational databases.

SQL, often expanded to Structured Query Language, is a standardized computer language that was originally developed by IBM for querying, altering and defining relational databases, using declarative statements.

* reasoning mechanisms are based on graph notions, basically the classical notion of graph homomorphism ; this allows, in particular, to link basic reasoning problems to other fundamental problems in computer science ( problems on conjunctive queries in relational databases, constraint satisfaction problem, ...),

A computer language like SQL presents an interesting case: it can be deemed a domain-specific language because it is specific to a specific domain ( in SQL's case, accessing and managing relational databases ), and is often called from another application, but SQL has more keywords and functions than many scripting languages, and is often thought of as a language in its own right, perhaps because of the prevalence of database manipulation in programming and the amount of mastery required to be an expert in the language.

In relational database theory, the term sublanguage, first used for this purpose by E. F. Codd in 1970, refers to a computer language used to define or manipulate the structure and contents of a relational database management system ( RDBMS ).

A monograph on this topic summarizes an extensive amount of published research in this area up to 1986, including subsections in the following areas: computer modeling in biology and medicine, arterial system models, neuron models, biochemical and oscillation networks, quantum automata, quantum computers in molecular biology and genetics, cancer modelling, neural nets, genetic networks, abstract categories in relational biology, metabolic-replication systems, category theory applications in biology and medicine, automata theory, cellular automata, tessellation models and complete self-reproduction, chaotic systems in organisms, relational biology and organismic theories.

Different areas, such as linguistics, relational algebra, and computer science incur renaming actions with different detailed activity, however the principles behind are all the same — change the name of something.

It is used in the general sense of computer-configured controls, where a computer system is interposed between the operator and the final control actuators or surfaces.

In this mode PPP is often not supported by the mobile phone operator but if the mobile is used as a modem to the connected computer, PPP is used to tunnel IP to the phone.

In computer science, it is the remainder operator that is usually indicated by either "%" ( e. g. in C, Java, Javascript, Perl and Python ) or " mod " ( e. g. in Pascal, BASIC, SQL, Haskell ), with exceptions ( e. g. Excel ).

In computer programming languages, the definitions of operator and operand are almost the same as in mathematics.

Historically, the term system operator applied to operators of any computer system, especially a mainframe computer.

This key can be traced back to the operator interrupt key used on IBM 3270-type console keyboards of the IBM System / 370 mainframe computer, which was used to cause the operating system such as VM / 370 or MVS to allow the console to give input to the operating system.

Such laws make it illegal for anyone other than the owner or operator of a computer to install software that alters Web-browser settings, monitors keystrokes, or disables computer-security software.
