Test: Turing Machine-Notation And Transition Diagrams

A turing machine is abstract or hypothetical machine thought by mathematician Alan Turing in 1936 capable of simulating any algorithm, however complicated it is.

 The turing machine operates on an infinite memory tape divided into cells. The machine positions its head over the cell and reads the symbol.

After the read head reads the symbol from the input tape, it performs the following functions:
a) writes a symbol(some model allow symbol erasure/no writing)
b) moves the tape left or right (some models allows no motion)
c) proceeds with subsequent instruction or goes either into accepting halting state or rejecting halting state.

The turing machine was invented by Alan turing in 1936. He named it as a-machine(automatic machine).

 Invention of turing machine answered a lot of questions which included problems like decision problem, etc.) . Alan was able to prove the properties of computation using such model.

Turing Completeness the ability for a system of instructions to simulate a Turing machine. A programming language that is Turing complete is theoretically capable of expressing all tasks accomplishable by computers; nearly all programming languages are Turing complete.

 We can represent a turing machine, graphically, tabularly and diagramatically.

A n abstract machine also known as abstract computer, is a theoretical model of computer or hardware system in automata theory. Abstraction in computing process usually assumes a discrete time paradigm.

 A thought experiment considers some hypothesis, theory or principle for the purpose of thinking through its consequences.

 In computer science, Random access machine is an abstract machine in the general class of register machines. Random access machine should not be confused with Random access memory.
