In computer science, a computation is the evolution over time of a computer. However, the meaning of the word "computer" should be understood here in a large sense, since it does not apply only to digital computers. A typical example of a physical computation is the evolution over time of a digital computer. Other examples of physical computations are derived from quantum computers or molecular computers. In computer science, which is sometimes described as the discipline that studies computations, mathemat ...

Originally, the word computing was synonymous with counting and calculating, and a science that deals with the original sense of computing mathematical calculations. "Computing" has come to mean the operation and usage of computing machines, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them (computer science). The following definition of computing is gi ...

The conceptual design above could be implemented using a variety of different technologies. As previously mentioned, a stored program computer could be designed entirely of mechanical components like Babbage's. However, digital circuits allow Boolean logic and arithmetic using binary numerals to be implemented using relays - essentially, electrically controlled switches. Shannon's famous thesis showed how relays could be arranged to form units called logic gates, implementing simple Boolean operations. Others soon figured out that vacuum tub ...

In computer science, computability theory is the branch of the theory of computation that studies which problems are computationally solvable using different models of computation. Computability theory differs from the related discipline of computational complexity theory, which deals with the question of how efficiently a problem can be solved, rather than whether it is solvable at all. Computability theory computation - Introduction. A central question of computer science is to address the limits o ...

Utility computing is a business model whereby a service provider makes available computer resources to their clients and charges them for the usage rather than the hardware. Like you pay the gas company or the electric company for its service based on usage, computing resources are metered and the user charged on that basis. A related term is On Demand Computing.

Affective computing is computing that relates to, arises from, or deliberately influences emotion. In the simple case, this may be a computational device helping communicate the emotions of its user, either for personal reflection, or to increase the bandwidth of communication between people. More complex affective computing technology can recognize and respond to the emotion of a user, such as adjusting the presentation of a computerized tutor when a learner is bored, interested, frustrated, or pleased. Another area within affective computing is the building of com ...

Computer science, an academic discipline (abbreviated CS , CSC, or Comp. Sci.), is a body of knowledge generally about computer hardware, software, computation and its theory. The discipline focuses on the management of the complexity in the construction and analysis of computer systems. The computer's operating system controls the hardware by its software with algorithms. Software involves a study of computer languages and programming paradigms, which further involves mathematical practices and abstraction. Hardw ...

Computational semiotics is the application of semiotics to computing machinery. It is the attempt to expand the realm of useful, computationally tractable logical operations, extending computer science past data processing into full semiosis. It may be understood as a kind of inquiry into artificial intelligence and knowledge representation but rooted in sign theory. One part of this field, known as algebraic semiotics, combines aspects of algebraic specification and social semiotics, and has been applied to user inte ...

DNA computing is a form of computing which uses DNA and molecular biology, instead of the traditional silicon-based computer technologies. A single gram of DNA with volume of 1 cm³ can hold as much information as a trillion compact discs. This field was initially developed by Leonard Adleman of the University of Southern California. In 1994, Adleman demonstrated a proof-of-concept use of DNA as form of computation which was used to solve the seven-point Hamiltonian path problem. Since the initial Adleman experiments, advances have been made, and various T ...

A computer language is a language used by, or in association with, computers. Often, the term is used synonymously with programming language, but in general a computer language need not be a programming language.
