Outline of computer science
Appearance
Computer science, or computing science, is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. One well known subject classification system for computer science is the ACM Computing Classification System devised by the Association for Computing Machinery. A separate list of basic topics in computer science include:
Nature of computer science
Branches of computer science
Mathematical foundations
- Mathematical logic - Boolean logic and other ways of modeling logical queries; the uses and limitations of formal proof methods
- Number theory - Theory of proofs and heuristics for finding proofs in the simple domain of integers. Used in cryptography as well as a test domain in artificial intelligence.
- Graph theory - Foundations for data structures and searching algorithms.
- Type Theory - Formal analysis of the types of data, and the use of these types to understand properties of programs — especially program safety.
Theory of computation
- Automata theory - Different logical structures for solving problems.
- Computability theory - What is calculable with the current models of computers. Proofs developed by Alan Turing and others provide insight into the possibilities of what may be computed and what may not.
- Computational complexity theory - Fundamental bounds (especially time and storage space) on classes of computations.
- Quantum computing theory -
Algorithms and data structures
- Analysis of algorithms - Time and space complexity of algorithms.
- Algorithms - Formal logical processes used for computation, and the efficiency of these processes.
- Data structures - The organization of and rules for the manipulation of data.
Programming languages and compilers
- Compilers - Ways of translating computer programs, usually from higher level languages to lower level ones.
- Programming languages - Formal language paradigms for expressing algorithms, and the properties of these languages (e.g. what problems they are suited to solve).
Concurrent, parallel, and distributed systems
- Concurrency - The theory and practice of simultaneous computation; data safety in any multitasking or multithreaded environment.
- Distributed computing - Computing using multiple computing devices over a network to accomplish a common objective or task and there by reducing the latency involved in single processor contributions for any task.
- Parallel computing - Computing using multiple concurrent threads of execution.
Software engineering
- Formal methods - Mathematical approaches for describing and reasoning about software designs.
- Software engineering - The principles and practice of designing, developing, and testing programs, as well as proper engineering practices.
- Reverse engineering - The application of the scientific method to the understanding of arbitrary existing software
- Algorithm design - Using ideas from algorithm theory to creatively design solutions to real tasks
- Computer programming - The practice of using a programming language to implement algorithms
Computer architecture
- Computer architecture - The design, organization, optimization and verification of a computer system, mostly about CPUs and Memory subsystem (and the bus connecting them).
- Computer organization - The implementation of computer architectures, in terms of descriptions of their specific electrical circuitry
- Operating systems - Systems for managing computer programs and providing the basis of a useable system.
Communications
- Game theory - Recently game theory has drawn attention from computer scientists because of its use in artificial intelligence and cybernetics.
- Networking - Algorithms and protocols for reliably communicating data across different shared or dedicated media, often including error correction.
- Cryptography - Applies results from complexity, probability and number theory to invent and break codes.
Databases
- Relational databases -
- Data mining - Study of algorithms for searching and processing information in documents and databases; closely related to information retrieval.
Artificial intelligence
- Artificial intelligence - The implementation and study of systems that exhibit an autonomous intelligence or behaviour of their own.
- Automated reasoning - Solving engines, such as used in Prolog, which produce steps to a result given a query on a fact and rule database.
- Robotics - Algorithms for controlling the behavior of robots.
- Computer vision - Algorithms for identifying three dimensional objects from a two dimensional picture.
- Machine learning - Automated creation of a set of rules and axioms based on input.
