In computability theory, there is a closely related concept known as Turing equivalence. Two computers P and Q are called Turing equivalent if P can simulate Q and Q can simulate P. Thus, a Turing complete system is one that can simulate a Turing machine, but the term is most often used to mean Turing equivalent to a Turing machine. The reason is that any real world computer can be simulated by a Turing machine, an observation codified as the Church Turing thesis .

Image Turingswitch.png right thumb 200px Turing switch The Turing switch is a logical construction similar to the Turing machine . The Turing switch models the operation of a basic network switch in a network of switches, much the same as a Turing machine models the operation of a basic computational entity. Both are named in honor of the English logician Alan Turing . Some introductory research on the Turing switch was started at the University of Cambridge by http www.cl.cam.ac.uk jac22 Jon Crowcroft . In essence, Crowcroft suggests that instead of using general purpose computers to do packet switching, the required operations should be reduced to application specific logic and then that application specific logic should be implemented using optical components. The work is not actually based on Turing s research. A Turing switch consists of a Switched fabric switching fabric , one or more ingress interfaces also referred to as sources , one or more egress interfaces sinks , and a decision procedure to determine an egress interface given an ingress interface. Interfaces are sometimes referred to as ports. A packet cell or switched unit arrives at an ingress interface, the appropriate egress interface is determined by the decision procedure, and the packet is then transported across the switching fabric to the egress interface. A packet is a symbol or sequence of 1 s and 0 s. An ingress interface is connected to an ingress line, an egress interface to an egress line. The ingress line is said to feed the ingress interface the egress interface feeds the egress line. ref Jon Crowcroft http www.cl.cam.ac.uk techreports UCAM CL TR 556.pdf Turing Switches.

refimprove article date June 2008 A Turing tarpit is any programming language or computer interface that allows for a great deal of flexibility in function but is difficult to learn and use because it offers little or no support for common tasks. The phrase was coined by Alan Perlis in the epigram quote 54. Beware of the Turing tar pit in which everything is possible but nothing of interest is easy. Alan Perlis Epigrams on Programming ref http www pu.informatik.uni tuebingen.de users klaeren epigrams.html Epigrams on Programming , SIGPLAN Notices Vol. 17, No. 9, September 1982, pages 7 13. ref In any turing completeness Turing complete language, it is possible to write any computer program, so in a very rigorous sense nearly all programming languages are equally capable. Turing tarpits prove that theoretical ability is not the same as usefulness in practice. A clear way of measuring this difference is by comparing the average lengths of common programs implemented in different systems. However, a very short version of a program may also be very hard to read. Turing tarpits are characterized by having a simple abstract machine which requires the user to deal with many details in the solution of a problem. At the extreme opposite are interfaces which can perform very complex tasks with little human intervention but become obsolete if requirements change slightly. Some esoteric programming languages , such as brainfuck , are specifically referred to as Turing tarpits , meaning they purposefully implement a minimum of functionalities to be classified as a Turing complete language.

In computability theory , the Turing jump or Turing jump operator , named for Alan Turing , is an operation that assigns to each decision problem math X a successively harder decision problem math X &prime with the property that math X &prime is not decidable by an oracle machine with an oracle computer science oracle for math X . The operator is called a jump operator because it increases the Turing degree of the problem math X . That is, the problem math X &prime is not Turing reducible to math X . Post s theorem establishes a relationship between the Turing jump operator and the arithmetical hierarchy of sets of natural numbers. Informally, given a problem, the Turing jump returns the set of Turing machines which halt when given access to an oracle that solves that problem.
