# What is an Turing Machines?

A Turing Machine is theoretical device of significance in computer science. It has a tape which extends infinitely in both directions and a recording head which can read and write one symbol at a time on the tape. The number of symbols it can read and write is finite. The head can also move in either direction on the tape one step at a time. The machine also a finite set of rules and a memory. Each rule takes the current symbol on the tape in combination with what is in the memory and from that says what symbol should be written, what the new content of the memory should be, and which direction the head should move. The device is significant because it is believed that any problem which can be solved by any computer can also be solved by a Turing Machine. Thus, a Turing Machine is considered a sort of minimalist computer. Also, devices or computational systems which are believed to be capable of solving these generalized problems are said to be "Turing Complete".

### What is the difference between a Turing machine and a universal Turing machine?

A Turing machine is a machine that can perform any possible computation, and emulate any real world computer, except other Turing machines. A Universal Turing machine however, is a theoretical machine that could even emulate Turing Machines. In actuallity they're both the same, since if you fed the tape from a Turing machine into another Turing machine, the second would in essence be emulating the first. Its also useful to note that Turing machines aren't…

### What is the Turing machine?

The Turing Machine is a hypothetical computer used by Alan Turing in his paper "On Computable Numbers" in his proof of the "Halting Problem" to show that there are some set of problems that no computer can solve, even if it has infinite memory and infinite time. The basic Turing Machine has a data memory composed of an infinitely long "tape" composed of "cells", each containing one symbol from a finite set of symbols. A…

### Which of the following is not a programming language?

(A) Basic (b) Turing (c) Java Of these three choices, (B) Turing is not a programming language. Turing was a mathematician that defined the rules for a "complete" computer/programming language/etc. His contributions to computer programming included the definition for a "complete" language (one that could possibly simulate any real-world condition/environment/etc, irrespective of being able to run in real-time, just being able to calculate the state thereof), and defining two "comparable" machines, such that one machine…
