[download pdf] Computation: Finite and infiniteIn our ordinary discourse, we distinguish between physical systems that perform computations, such as computers and calculators, and physical systems that don't, such as rocks. Among computing devices, we distinguish between more and less powerful ones. These distinctions affect our behavior: if a device is computationally more powerful than another, we pay more money for it. What grounds these distinctions? What is the principled difference, if there is one, between a rock and a calculator, or between a calculator and a computer? Answering these questions is more difficult than it may seem. In addition to our ordinary discourse, computation is central to many sciences.

A Turing machine is a mathematical model of computation that defines an abstract machine ,  which manipulates symbols on a strip of tape according to a table of rules. The machine operates on an infinite  memory tape divided into discrete "cells". Then, as per the symbol and its present place in a "finite table"  of user-specified instructions, the machine i writes a symbol e. The Turing machine was invented in by Alan Turing ,   who called it an "a-machine" automatic machine. Thus, Turing machines prove fundamental limitations on the power of mechanical computation. Turing completeness is the ability for a system of instructions to simulate a Turing machine.
