Extensive Definition
Computation is a general term for any type of
information
processing that can be represented mathematically. This
includes phenomena ranging from human thinking to calculations with
a more narrow meaning. Computation is a process following a
welldefined model
that is understood and can be expressed in an algorithm, protocol,
network
topology, etc.
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:
Different mathematical models of computers
can be classified according to their expressive power, see the
Chomsky
hierarchy.
History
The word computation has an archaic meaning (from
its Latin
etymological roots), but the word has come back in use with the
arising of a new scientific discipline: computer
science.
