What is the language of a Turing machine?
The language of a TM is defined as the set of all the strings it accepts. Not every language is the language of a Turing machine – that’s one of the landmark results of theoretical computer science.
How would you describe a Turing machine?
- A Turing machine is a mathematical model of computation that defines an abstract machine that 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”.
Which grammar is accepted by Turing machine?
A language is recursively enumerable (generated by Type-0 grammar) if it is accepted by a Turing machine. A TM decides a language if it accepts it and enters into a rejecting state for any input not in the language. A language is recursive if it is decided by a Turing machine.
Which type of grammar is most unrestricted form of grammar?
Type 0 Grammar
What are the applications of Turing machine?
Turing machines founds applications in algorithmic information theory and complexity studies, software testing, high performance computing, machine learning, software engineering, computer networks and evolutionary computations.

Which of the following is correct for Chomsky hierarchy?
3. Which of the following relates to Chomsky hierarchy? Explanation: All the regular languages are the subset to context free languages and thus can be accepted using push down automata. 5.
What are the components of a Turing machine?
A Turing machine consists of (a) a finite control, (b) one tape, representing the memory, that has a left margin and is divided into an infinite number of cells, and (c) a moving read/write head. The finite control can be in any one of a finite set Q of states.
What is the basic difference between 2 way FA and TM?
Statement: Turing Machine can change symbols on its tape, whereas the FA cannot change symbols on tape. Explanation: The following mentioned is the difference between 2-way FA and TM. Another instance is that TM has a read/write tape head while FA doesn’t.

How is linear bounded automata different from Turing machine?
An LBA differs from a Turing machine in that while the tape is initially considered to have unbounded length, only a finite contiguous portion of the tape, whose length is a linear function of the length of the initial input, can be accessed by the read/write head; hence the name linear bounded automaton.
What is linear bounded automata with example?
A linear bounded automaton is a multi-track non-deterministic Turing machine with a tape of some bounded finite length. The computation is restricted to the constant bounded area.
Which language is accepted by linear bounded automata?
In 1964, Kuroda introduced the more general model of (nondeterministic) linear bounded automata, and showed that the languages accepted by them are precisely the context-sensitive languages. q states, m characters in the tape alphabet , and the input length is n.
What are the different components of a linear bounded automata?
called a linear-bounded automaton (LBA). A linear bounded automaton is a non-deterministic Turing machine M = (Q, Σ, Γ, δ, s, t, r ) such that: * There are two special tape symbols < and >(the left end marker and right end marker).
Are Multitape and multitrack Turing machines same?
Are Multitape and Multitrack turing machines same? Explanation: Multitrack turing machines are special types of Multitape turing machines. In a standard n-tape Turing machine, n heads move independently along n-tracks.
What is finite automata and its types?
Types of Automata: There are two types of finite automata: DFA(deterministic finite automata) NFA(non-deterministic finite automata)
Where is finite automata used?
Finite automata are used in text processing, compilers, and hardware design. Context-free grammar (CFGs) are used in programming languages and artificial intelligence. Originally, CFGs were used in the study of the human languages.
What is finite automata and its application?
Application of Finite Automata (FA): Some are given below; A finite automata is highly useful to design Lexical Analyzers. A finite automata is useful to design text editors. A finite automata is highly useful to design spell checkers. A finite automata is useful to design sequential circuit design (Transducer).
