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 is DFA used for?
DFA serves as the basis for various computer operations such as pattern matching, compiler construction, network protocols and text processing.
It is used in algorithms, scanners and parsers in compiler design, and in software applications like text editors, search engines and databases.A deterministic finite automaton (DFA) is a five-tuple M = (Q, Σ, δ, q0, F) with the components specified as follows: 1.
Q: A finite, nonempty set of states.
2Σ: The data alphabet and its induced tape alphabet ΣT = Σ ∪ {<,>}.
What is deterministic finite automata?
Deterministic finite automata (or DFA) are finite state machines that accept or reject strings of characters by parsing them through a sequence that is uniquely determined by each string.
The term “deterministic” refers to the fact that each string, and thus each state sequence, is unique.
