Push Down Automata (PDA) are a way to represent the language class called Context Free Languages(CFLs). PDA are abstract devices defined in automata theory. They are similar to Finite Automata(FA), except that they have access to a potentially unlimited amoun of memeory in the form of a single stack. PDA are of two types Deterministic and Non-Deterministic. Every PDA excepts a Formal Language. The language accepted by non-deterministic PDA are precisly the CFLs. If we allow a finite automaton to access two stack instead of just one, we obtain a device much more powerful than a PDA, equivalent to a Turing Machine(TM).

How to design a finite automata to accept a palindrome no?
Design a pushdown automata for the same. Otherwise, you can use the following grammer : S -> aSb|bSa|<NULL>
What is dfa and nfa?
DFA - Deterministic Finite Automata NFA - Non-Deterministic Finite Automata Both DFAs and NFAs are abstract machines which can be used to describe languages.
What you mean by Finite Automata?
Finite automata are machines used to recognize patterns from input set of characters. They either reject or accept inputs based on the already defined pattern set by the FA.
What study in logic and automata?
Studying logic in the context of automata theory typically involves exploring formal languages, regular and context-free grammars, finite automata, and Turing machines. It aims to understand how logic can be used to model computation and language recognition, leading to applications in areas such as compiler design, artificial intelligence, and formal verification. This field provides fundamental tools for analyzing the computational capabilities of machines and systems.
Define the languages accepted by NFA and DFA?
In general, finite state machines can model regular grammars. Deterministic finite automata can represent deterministic context-free grammars. Non-deterministic finite automata can represent context-free grammars.
When was Automata released?
Automata was released on 12/31/2014.
When did Automata UK end?
Automata UK ended in 1985.
What was the Production Budget for Automata?
The Production Budget for Automata was $15,000,000.
In what order the elements of a pushdown stack are accessed?
Stack
Is the main purpose of using Automata?

How is finite state automata used in computer science?
They are used to make state machines that control sequences of operations: e.g. syntax parsing, communication protocols, user interfaces.
Who invented the automata?
the greeks
