Short description: Overview of and topical guide to computer science
Computer science (also called 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.
Computer science can be described as all of the following:
Subfields
Mathematical foundations
Algorithms and data structures
- Algorithms – Sequential and parallel computational procedures for solving a wide range of problems.
- Data structures – The organization and manipulation of data.
Artificial intelligence
Outline of artificial intelligence
- Artificial intelligence – The implementation and study of systems that exhibit an autonomous intelligence or behavior 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, and automated theorem provers that aim to prove mathematical theorems with some assistance from a programmer.
- Computer vision – Algorithms for identifying three-dimensional objects from a two-dimensional picture.
- Soft computing, the use of inexact solutions for otherwise extremely difficult problems:
- Machine learning - Development of models that are able to learn and adapt without following explicit instructions, by using algorithms and statistical models to analyse and draw inferences from patterns in data.
- Evolutionary computing - Biologically inspired algorithms.
- Natural language processing - Building systems and algorithms that analyze, understand, and generate natural (human) languages.
- Robotics – Algorithms for controlling the behaviour of robots.
Communication and security
- Networking – Algorithms and protocols for reliably communicating data across different shared or dedicated media, often including error correction.
- Computer security – Practical aspects of securing computer systems and computer networks.
- Cryptography – Applies results from complexity, probability, algebra and number theory to invent and break codes, and analyze the security of cryptographic protocols.
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).
- Operating systems – Systems for managing computer programs and providing the basis of a usable system.
Computer graphics
- Computer graphics – Algorithms both for generating visual images synthetically, and for integrating or altering visual and spatial information sampled from the real world.
- Image processing – Determining information from an image through computation.
- Information visualization – Methods for representing and displaying abstract data to facilitate human interaction for exploration and understanding.
Concurrent, parallel, and distributed systems
- Parallel computing - The theory and practice of simultaneous computation; data safety in any multitasking or multithreaded environment.
- Concurrency (computer science) – Computing using multiple concurrent threads of execution, devising algorithms for solving problems on multiple processors to achieve maximal speed-up compared to sequential execution.
- Distributed computing – Computing using multiple computing devices over a network to accomplish a common objective or task and thereby reducing the latency involved in single processor contributions for any task.
Databases
Outline of databases
- Relational databases – the set theoretic and algorithmic foundation of databases.
- Structured Storage - non-relational databases such as NoSQL databases.
- Data mining – Study of algorithms for searching and processing information in documents and databases; closely related to information retrieval.
Programming languages and compilers
Scientific computing
Software engineering
Outline of software engineering
- Formal methods – Mathematical approaches for describing and reasoning about software design.
- Software engineering – The principles and practice of designing, developing, and testing programs, as well as proper engineering practices.
- 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.
- Human–computer interaction – The study and design of computer interfaces that people use.
- Reverse engineering – The application of the scientific method to the understanding of arbitrary existing software.
Theory of computation
- Main page: 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 – Explores computational models involving quantum superposition of bits.
