Computation is a general term for any type of information processing that can be represented mathematically. This includes phenomena ranging from simple calculations to human thinking. In a more narrow meaning, computation is a process following a well defined Model (abstract) that is understood and can be expressed in an algorithm, Protocol (computing), network topology, etc.
Classes of computation Computation can be classified by at least three orthogonal criteria: digital vs analog electronics, sequential vs parallel computation, batch processing vs interactive computation.
In practice, digital computation is often used to simulate natural processes (for example,Evolutionary computation), including those that are more naturally described by analog models of computation (for example, Artificial neural network). In this situation, it is important to distinguish between the mechanism of computation and the simulated model.
Computations as a physical phenomenon A computation can be seen as a purely physical phenomenon occurring inside a closed physical system called a computer.Examples of such physical systems include digital computers, quantum computers, DNA computers, molecular computers, analog computers or wetware computers.This point of view is the one adopted by the branch of theoretical physics called the physics of computation.
An even more drastic point of view is the postulate of digital physics that the evolution of the universe itself is a computation.
Mathematical models of computation In the theory of computation, mathematical models of computers are defined. A computation is the evolution over discrete time epochs of this model.Typical mathematical models of computers are the following:
- Turing Machine
- push-down automaton
- Finite state automaton
History The word computation has an archaic meaning (from its Latin language etymological roots), but the word has come back in use with the arising of a new scientific discipline: computer science.
