What is DFA and NFA?
DFA stands for Deterministic Finite Automata. NFA stands for Nondeterministic Finite Automata. For each symbolic representation of the alphabet, there is only one state transition in DFA. No need to specify how does the NFA react according to some symbol.
What are the different types of languages in automata?
A finite automaton (FA) is a simple idealized machine used to recognize patterns within input taken from some character set (or alphabet) C. The job of an FA is to accept or reject an input depending on whether the pattern defined by the FA occurs in the input. A finite automaton consists of: a finite set S of N states.
What do you mean by formal language?
Definition of 'formal language' 1. a language designed for use in situations in which natural language is unsuitable, as for example in mathematics, logic, or computer programming. The symbols and formulas of such languages stand in precisely specified syntactic and semantic relations to one another.
In automata theory, a formal language is a set of strings of symbols drawn from a finite alphabet. A formal language can be specified either by a set of rules (such as regular expressions or a context-free grammar) that generates the language, or by a formal machine that accepts (recognizes) the language.
