Classes of computation
Computation can be classified by at least three orthogonal criteria: digital vs analog, sequential vs parallel, batch vs interactive. 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. Computation is a form of calculation, the procedure of calculating; determining something by mathematical or logical methods or problem solving that involves numbers or quantities.
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
Different mathematical models of computers can be classified according to their expressive power, see the Chomsky hierarchy.

If you had only an ego and the id, then the id's impulses would always be satisfied. If you had only an ego and superego, then the superego's urgings would always be met. But in fact, most of us have all three. Thus, the ego serves to balance the demands of the id against those of the superego by realistically assessing the limits imposed by the real world. The ego serves an executive function to maximize the benefits to the whole person.
